Adam Sandler: Put on Your Yarmulke ... Let's Party!!!

Adam Sandler is to Hanukkah what Mariah Carey is to Christmas, so it's no surprise his holiday party was epic ... and long.

Sandler threw the shebang for his Happy Madison employees Thursday night at Pickwick Gardens in Burbank, and it was stacked with stars, including David Spade, Josh Gad, Joey Fatone, Taylor Lautner, Patrick Schwarzenegger, Jon Lovitz, Tom Morello and Courtney Love.

Lots to do ... an ice rink, bowling and games, but the real entertainment was Sandler who hopped on the mic with KISS singer and bassist Gene Simmons. Turns out ... they were just the opening act for Vanilla Ice.

On the menu ... pigs in a blanket, mac and cheese, chicken fingers, pasta, pizza, subs, a Chinese buffet and an entire room filled with desserts.
