Rondell Sheridan

Comedian Rondell Sheridan likes to joke that everyone in a relationship has thought about killing his or her partner at some point. For Sheridan, who describes men as a "penis and a pair of eyes," often describes romantic relationships in his routines, which rely on observational humor. The fast-talking comic performs tonight at 7:30 and 10 p.m. at the Hard Rock Rocksino Northfield Park's Club Velvet, where he has shows scheduled through Sunday. Tickets are $13 to $18. (Niesel)
