Deon Butler remembers vividly his first trip to Wisconsin's Camp Randall Stadium, and the Badgers' signature "Jump Around" by House of Pain.

The routine for Wisconsin fans is rigid.

Every home game, at the end of the third quarter, "Jump Around" is piped through Camp Randall's speakers. Each time, students and alumni pogo for a few minutes.

"The whole stadium jumping around like that is crazy," Butler said.

Penn State will experience it again Saturday when it travels to Wisconsin for an 8 p.m. kickoff.

The tradition, one of several that make Madison, Wis., many of the players' top road trips, almost permanently ended five years ago.

Wisconsin finished construction at the end of the 2002 season that included skyboxes surrounding the stadium, and university officials decided to cancel "Jump Around."

The students were never told, and when the fourth quarter began, the crowd jumped around anyway. Protests began almost immediately, and gestures were directed toward the sound booth.

Two days later, after petitions circulated around campus, Wisconsin chancellor John D. Wiley announced the tradition would resume after he was reassured no structural damage would occur.

At the time, Wiley said some fans were uneasy by the upper deck swaying when students jumped around.

"Because of the many concerns raised, I'm asking upper-deck fans to refrain from jumping out of consideration for their neighbors and to take the opportunity, instead, to cheer on the student section," Wiley said in a news release issued two days after the tradition was cut.

As most Penn State players have experienced, "Jump Around" is a small part of the Camp Randall experience.

"That's their trademark, which is kind of like our 'Hey Baby,' " Penn State director of branding and marketing Guido D'Elia said. "I think they're loud, they make themselves heard, they're somewhat outrageous."

Wisconsin also is known for an unconventional wave the student section begins by having a wave go around the stadium once counter-clockwise, then once in slow motion, once more after doubling the speed, reversing the wave and then dividing it into two.

Fans at Camp Randall, the oldest Big Ten stadium, have also escalated the intensity by showering visiting players with batteries or nickel-stuffed marshmallows.

The mood isn't always as hostile. Butler said fans cracked jokes and talked about him two years ago, something he called good-natured ribbing but also a nuisance.

"Every time you come to the sideline, the fans are right there cracking jokes while you're trying to listen to what needs to be done on the next series," Butler said.

Wisconsin and Penn State have carved out their own niche in making their home stadiums unique.

The Nittany Lions have 'Hey Baby.'

Wisconsin has 'Jump Around.'

Penn State has the whiteouts.

Wisconsin has 80,000 fans wearing red.

"I think we're a little more consistent," D'Elia said. "We try to do things that carry over for a lot more of the game and spread the involvement beyond the student section."

Another difference, D'Elia said, is Wisconsin's fan base has a longer reputation as one of the best in the country. Penn State's has quickly ascended into the national spotlight after D'Elia incorporated the whiteout and other in-game aspects, such as Kernkraft 400 by Zombie Nation when Penn State's fans jump.

Wisconsin, though, has steadily built its reputation at making a 91-year-old stadium a difficult place to play.

"It's a rough crowd with a hard edge," D'Elia said. "They make themselves heard, and I would expect in a night game they would do that. I certainly hope we're able to play in a way that would take the air out of the balloon and take the crowd out of the game."

Wisconsin's reputation has tangible effects throughout the game. Quarterback Daryll Clark might use more hand signals for routes, something Penn State hasn't had to use often because atmospheres at Syracuse and Purdue weren't as loud. The offensive line also might go to a silent snap count.

"Basically, other than that, it's still a football game," Butler said.

Just one played in an environment defensive end Josh Gaines described as "crazy, it's wild."

Gaines' first road trip his true freshman season was in Madison, Wis. He heard the chants and "Jump Around," and he saw the wave.

"They're right up on you, and they stay on you the whole game," Gaines said. "It's a rough atmosphere, and not too many guys have gone out there and played. This'll be the most hostile environment we've seen all year."

Gaines said he thrives on the potential hostility.

"Oh, yeah," Gaines said. "I like the negative attention. It's fun. We all actually like it, especially the d-line. We love that stuff. We get so much love here at home, but when you get the negative chants, it's fun."

The environment should also be one of the most memorable. Safety Drew Astorino has heard from teammates how fun Madison, Wis., can be, and wide receiver Jordan Norwood said Camp Randall is one of his favorite road trips along with Ohio State.

D'Elia has been to Madison twice, and said the only comparable road venue is Ohio State. Minnesota can also be loud because of playing in a dome.

Even Joe Paterno, who broke his left leg and tore ligaments in his left knee after a sideline collision in 2006, can appreciate the backdrop for Saturday night.

"They're going to go out there before a great stadium, a great crowd, very enthusiastic, very partisan," Paterno said. "And I mean, if you don't like that, why do you come to Penn State? So I think it should be a fun Saturday for a kid 18, 19, 20, 21 going against good football players on national television at night. ... You dream about those things when you're 14 or 15 years old. So now they have an opportunity, and I think it should be a heck of a night."
