Say goodbye to Preparation H Raymond, the Fed Ex Pope and Sexual Harassment Skeleton.

Sadly, after 15-and-a-half years, Late Night with Conan O'Brien goes off the air tonight, marking the end of one of the great eras in comedic history.

Sure, Conan's going to return to the air in June as host of the Late Show, but it won't be the same; his act will be forced to change.

Instead of appealing to the crowd normally awake at 1 a.m. (i.e. us college students), Conan will have to adapt to the new timeslot and the subsequent older audience. Instead of performing for mainly college students and young adults, Conan's viewership will stretch across a wider, more conservative demographic (i.e. older folks and younger children).

Conan will have to be careful not to offend his viewers and advertisers, so no more Horny Manatee, Quackers the poop-eating duck or Triumph the Insult Comic Dog. They're just too risqué for the 11:30 p.m. timeslot.

Of course we'll still get to see staples like "In the Year 2000," the string dance and La Bamba, but a part of our young lives is coming to an end, and, I gotta say, it's making me feel kind of old.

My GPA has probably taken a couple percentage points hit because of Conan distracting me from my studies, but it was worth it. No matter how crappy a day I had had or how many problems were running through my head, I always knew at 12:30 I could forget all my worries and just laugh for an hour of pure comedy.

We grew up with Conan, and he's grown with us. The first three years of his show left a lot to be expected. He looked nervous on camera and was so inconsistent his contract with NBC had to be renewed on a weekly basis.

But then he found his niche, and it just so happened to mesh perfectly with our generation. As a whole we like thoughtless, spontaneous humor, and Conan delivered.

Who else would drink a 40 of Olde English with Martha Stewart on the air?

Who would fly down a zip line to kick John Wilkes Booth before he could assassinate Abraham Lincoln?

Who came up with the Walker Texas Ranger lever long before Chuck Norris became synonymous with God on college campuses?

One man: Conan.

For graduating seniors like myself, maybe this is a good move. Instead of having to stay up until 1:30 to catch the end of Conan, we'll be able to catch one of the funniest talk shows on television and still be in bed in time to get up for work.

But something definitely will be missing. Conan will still be there, as will Max Weinberg and the Max Weinberg Seven, but the edge will be gone.

I'm sure Conan will still be funny -- he is after all a gifted humorist -- but it will be a different kind of funny. Hopefully I'm wrong, but deep down I know I'm right.

So be sure to set your DVRs and savor this last episode, because if there's one thing we can expect from Conan it's that we never know how far he'll go to get a laugh. And thanks to political correctness, we may never laugh this hard again.
