Broadway's buzzing about South Park creators Trey Parker and Matt Stone's new Broadway musical, The Book of Mormon, and celebrity fans have began descending upon the Eugene O'Neill Theatre to take in the show for themselves. On March 11, Broadway veteran and current Glee guest star John Stamos as well as Jim Belushi (who will make his Broadway debut later this month in Born Yesterday) joined Parker and Stone after a Mormon performance to clown around at the theater's neighboring Serafina restaurant. The comedic crew couldn't help but give our camera a few goofy faces during their meet-up. Join the fun below!
