50 cent and models at Vitaminenergy's Naked Ping Pong Celebrity tournament. Scottsdale, Arizona - 31.01.08

Kimmel's comedy sidekick Guillermo stripped naked and challenged the rapper to a game at 50's pre-Super Bowl party in Scottsdale, Arizona.

But when the chubby Latino caught a ping pong ball to the genitals, he told the rap star he was "very tired", prompting a smiling 50 Cent to hand him a can of his new energy drink.

Upon sipping the drink, Guillermo developed super-human strength and beat the rapper.
