It's all fun and games until someone gets bit in the scrotum.  In Boiling Springs, Pennsylvania, 27-year-old Nicholas Sworen and a 32-year-old man were drinking at the man's house . . . and ended up getting into a drunken brawl.

--The brawl ended after Nicholas hit the man in the head with a beer bottle . . . and then clamped his teeth down on the guy's package.  Nicholas was arrested for simple assault . . . police didn't say if the other man was hospitalized.
