Cam'ron I Obliterated a Guy's Nuts For Only 20 Bucks

Rapper Cam'ron kicked some dude's testicles into the back of his throat Monday night in Vegas ... and it only cost him a reasonable $20.

Here's how it all went down. Cam'ron ran into a ballsy street peddler who was playing let's make a deal -- his sign read, "Kick me in the nuts ... $20."

Cam'ron accepted the gentleman's offer and delivered David Beckham style. The street peddler collapsed in pain, Cam'ron paid his debt and went on his merry way.

Capitalism ... you gotta love it.
