Jake Gyllenhaal in ‘Giving Up the Gun’ by Vampire Weekend
Jake Gyllenhaal looks for the performance-enhancing properties of hard liquor as he plays a whiskey-swigging tennis player in the video for 'Giving Up the Gun,' from Vampire Weekend's second album, 'Contra.' Lil Jon, RZA and Joe Jonas round out the cast of WTF cameos, making this clip the most star-studded entry on this celeb-heavy list.
"That was just amazing, because I love that band, and I love their first album, and I had recently just got their second album," Gyllenhaal told MTV News of his appearance in the clip. "It was really fun. I met the band and hung out with them. They're all really cool guys."
