Luckily for us, the following talk show blunders were too entertaining to leave on the cutting room floor.

“But people would always wonder,” he told the magazine.

“What’s real?

Regis Philbin and Kelly Rippa hosting their show

That’s what I do in my act, test how other people deal with reality.”

Letterman was visibly uncomfortable asKaufman stormed around the setdropping some choice four-letter words.

If this was one of Kaufman’s infamous acts, Letterman certainly wasn’t in on the joke.

In an interview withFilm Fad, Lawler had only pleasant things to say about Kaufman.

In 1995, Drew Barrymore was no longer just a child star.

It’s safe to assume Letterman is quite fond of the memory, as well.

Paul Rudd can’t stop pranking Conan

Fool me once, shame on you.

Fool me twice, shame on me.

Fool me three times c’mon, Paul Rudd.

That mystery may never be solved.

It’s a simple concept.

Rudd appears as a guest on O’Brien’s show to promote his current project.

The scene is a classic ’80s level of cheesy and, you guessed it, never once features Rudd.

Good thing O’Brien knows how to take a joke again, and again, and again.

Perhaps that explains why Jimmy Fallon is one of the most beloved talk show hosts on television.

It’s a moment that perfectly encapsulates the beauty of live, unscripted television.

Couric had a different plan.

As the segment begins, the English host cheerfully welcomes Couric to the show.

But Couric doesn’t come running she comes tumbling.

The woman on the ground?

A Katie Couric stunt double, of course.

Seeing unsuspecting audience members jumping for joy and crying happy tears is truly priceless.

It’s all fun and games until someone breaks a television, kids.

Then it’s hilarious.

Dance ‘til you drop

Dancing takes some serious skill.

Dancing in high heels takes some serious courage.

Dancing in high heels onThe Tonight Show with Jimmy Fallontakes you for a ride.

That is, if you’re Meghan Trainor.

We’ll take his word for it!

“I was afiend,” Stone says.

“I was obsessed with the Spice Girls.

They taught me about girl power and Ilovethem.”

A drum roll commences, Stone freezes in anticipation, and Norton finally spills the beans.

Stone is quite possibly the most relatable celebrity on Earth.

If your answer is “that one time onOprah,” you are Tom Cruise.

In a veryJim Halpert move, Oprah then looks directly into the camera.

“The boy has lost it,” she says.

Jackson’s Super Bowl show was a level three wardrobe malfunction.

Kelly Ripa’s zipper debacle onLive!

With Regis and Kellyis a level two wardrobe malfunction.

Being a woman is tough, and zippers don’t make the job any easier.

“I really think the zipper is stuck,” he says in a surprise to no one.

Zippers: therealfeminine mystique.
