Comedy video website Funny Or Die has always featured top celebs in their web projects, but this one in particular may have taken their tradition to new heights. In promoting the 10th anniversary of the Clinton Foundation, former President Bill Clinton makes a cameo in this A-list heavy video which features the likes of Ben Stiller, Matt Damon, Ted Danson, Sean Penn, Kristen Wiig, and Jack Black  to name a few.

In the video, the stars sit at a table to brainstorm ideas for the foundation’s “Celebrity Division.” Lead by Stiller, the brainstorming session becomes unproductive, with Matt becoming persistent in his desire to start a foundation softball team, while Sean Penn is ticked off that someone is eating his lunch that he’s marked with his name on it. 

The final scene of the video has the team pitching their new ideas over the phone to the president himself … or so they believe. We also find out who’s been stealing Penn’s lunch from the fridge. 

The event, held at the Hollywood Boulevard Mann’s Chinese Theater, was also attended by Four Christmases co-stars Katy Mixon, Sissy Spacek, Kristin Chenoweth, Mary Steenburgen (who brought along hubby Ted Danson as her date) and Jon Favreau.

New mom Minnie Driver also made an appearance, wearing a white lace-lined dress with see-through sleeves.

Noticeably absent was the male lead in the film, Vince Vaughn.

While initial reports had Reese Witherspoon seeming at odds with the much-taller Vaughn, 38, last night she told USA Today he was the “funniest co-star she’s ever had.”

Vince was said to be in Bora Bora working on another film.

Next up for Reese is the animated 3-D feature Monsters Vs. Aliens, which is set to be released in March 2009.
