Plot: It's the night of a reunion for Joey and Danny -- the reunion of Chi Sigma Sigma (CSS), the college fraternity they were in 10 years ago. Joey and Danny remember that the fraternity burned Danny's Chi Sigma Sigma jacket 10 years ago when Danny messed up and unintentionally allowed a sorority, Lambda Tau Delta (LTD), to steal the stuffed seal that was Chi Sigma Sigma's mascot
