Pierre -

In all your years of porn I'm sure you've said to yourself: "I feel like I'm in a comedy movie."

What's something hilarious that happened to you? A funny event?

Maybe a girl showed up in a ridiculous robot outfit asking to be fucked...

Or a girl said something to you while you were fucking that made you laugh...

There are plenty of compilation videos of old movie and video outtakes.
My favorite scene was a DP.
A man was on his back on the bottom with his dick in her ass. Above him was the woman. Above her was the man. He pulled out and stroked himself to climax. When he came, he covered the man's face with his sperm.
The disgusted look on the man's face was priceless.
