A fixture on MTV in the '80s, flamboyant comic Pauly Shore might be the man who popularized upspeak. His comedic style often borders on becoming completely obnoxious as he rapidly delivers lines that sound so unstructured, you gotta think he just makes much of his material up on the spot. Shore, who also once somehow wrangled a movie deal with Disney — a true mystery since he regally uses obscenities on stage — takes a casual, stream-of-consciousness approach to performing. Expect each show to be wildly different from the previous one. He takes the stage at 7:30 tonight at the Improv and has shows scheduled through Sunday. Tickets start at $25. (Niesel)
