Matt Damon, Bono, and LeBron Jame Bono made cameo appearances on last night’s season finale of Entourage to promote the charity ONEXONE.

Last week we caught a teaser leading up Damon’s appearance, when HBO showed a fake PSA in which Damon freaks out on Vince (played by Adrian Grenier). This week Damon once again showed his aggressive side when he kept asking Vince to donate money to ONEXONE and join him on a mission trip to promote the charity. When Vince only donates $10,000, Damon guilts him into giving more. When Damon realizes a larger donation still hasn’t been made, he leaves a series of hilarious and angry phone messages on Vince’s voicemail. Damon also nudges Vince’s brother Drama (played by Kevin Dillon) to donate as well, or as Drama called it ” he Jason Bourne’d me.” The show did a fantastic job of promoting the charity by weaving it into the story line.
