The Spike TV Guys Choice Awards take place this weekend, and the testosterone-heavy show always draws in big-name celebrities. Matthew McConaughey will be honored with guy of the year for 2014, and Sandra Bullock will receive the decade of hotness award on Saturday. In years past, stars like Jennifer Aniston, Brad Pitt, and Matt Damon have stopped by the bash to scoop up awards, joke around on stage, and mingle with their Hollywood pals. Things can get a little frisky during the show, too, like when Halle Berry made out with Jamie Foxx on stage in 2009 and when a giraffe got frisky with Olivia WIlde last year. Keep reading to see some of the best moments from the Guys Choice Awards over the past few years, and make sure to tune in to Spike TV on June 11 when the show airs at 9 p.m. EDT/PDT!
