CHAD KROEGER of Nickelback

The How You Remind Me rocker learned of his unique skill as a teenager when he was dared to do something outrageous for a crate of beer.

He tells Playboy magazine, "I put my own d**k in my mouth. I was 14 and much more flexible at the time.

"It was soft and required a lot of pulling. I really wanted that case of beer."
