Ice Cube to Rabbi -- For You, a Beatdown! Casino Fight Alleged

So a rabbi and Ice Cube walk into a casino, and the rabbi catches an anti-Semitic fueled ass whuppin' -- at least that's what the rabbi's claiming, but Cube says that's a load of crap.

P. Taras, who says he's a rabbi ... tells TMZ he was at the MGM Detroit on May 24 when he literally bumped into Cube outside an elevator.

Taras claims he said something like ... hey, watch out -- and the rapper/actor responded by having his boys attack. While he was getting stomped, Taras claims he heard several epithets. He thinks that's because he was wearing a yarmulke.

Taras has filed a lawsuit against Cube for assault and battery, and wants $2 million for his troubles.
