Rob Dyrdek Admits THIS Is The Dumbest Thing He's Ever Done

Hint: It involves two life-sized pieces of sh**.

Many claim to live life without regrets, but Rob Dyrdek, for one, genuinely doesn't have a trace of contrition within him.

Since opening up the "Fantasy Factory," the fearless stuntman has LARPed, licensed a bowel-movement buffet and launched dear Drama out of a human cannon -- all without apology. But on tonight's episode, he made a historic declaration: He wished he'd never executed his latest objective. Any guesses as to what it is?

Well, if you found yourself leaning toward "filming a mock hygiene PSA in which my friends and I dress up like pieces of sh**, dingleberries and fractions of lubricated toilet paper" as an answer, you're totally right, sir or madam!

In the video above, after screening the gang's...colorful?....production, Rob can't help but tear the "Dude Wipe" project to shreds.

"This thing's never gonna see the light of day," he asserts. "This is the dumbest thing I've ever come up with in my life." There's a first time for EVERYTHING, guys!

Check out the clip for one hell of a shocking admission, and be sure to watch Rob's coming adventures next Thursday night at 10/9c on MTV!
