Watch P. Diddy's Hilarious Reaction To Getting Pranked By Ellen DeGeneres

Never lie. Like ever, because you just don't know whether it's going to get put to the test one day. Remember when you said you could speak that really obscure language to get you through a job interview, or that you had some weird dietary requirement, or in P Diddy's case, saying that you're not scared of clowns.

And don't tell a fib especially when you're around Ellen DeGeneres because it won't end well, as P Dids found out when he went on her talk show where she had a man dressed as a clown set up inside a box ready to pounce.

When she broached the question, Diddy told her it was 'impossible' for him to be scared of clowns - why? According to the rapper the reason he isn't frightened is because he is a black man, adding: "I have so many other things to be fearful of, a clown is not gonna scare me."

Looking a little worried, possibly about how his reaction will be when faced with the impending fright - Ellen asked: "But I thought you were..."

And as if by magic a ginger-haired, white-faced, spooky-looking Pennywise jumps out of what looked like a coffee table.

And the reaction? Priceless.

It wasn't priceless because he pretty much shit himself on television. No, it was priceless because he transformed in front of our eyes from a fearless mother fucker to a karate kicking lunatic.

Then his weird as shit karate kick turned into some cheer-leading sequence with the only thing missing being his pink pom poms.

And he ended the bizarre show with a shuffle towards Ellen which mirrored something we would expect to see at a Bruno Mars concert.

As he calmed down (eventually) he told Ellen and the audience: "You know I woke up this morning and I said I want my life to be full of surprises."

He then thanked Ellen and gave her a hug, before she replayed the entire thing for him to watch.

And he didn't look too impressed at the fact that everyone now knows P. Diddy likes a good ol' dance when he's just had a fright.

Street cred 0 - 1 Ellen DeGeneres.
