Comedian Jim Breuer is best known for his stint on Saturday Night Live (who could forget Goat Boy?) and for the stoner epic Half-Baked, but he's really a family-friendly veteran stand-up full of surprises (heavy-metal holiday songs, anyone?). He performs at Helium Comedy Club, 2031 Sansom St. Times: 7:30 and 10 p.m. Friday and Saturday. Tickets: $32. Information: 215-496-9001 or www.heliumcomedy.com.
Fa la la la la - love stinks

Dancing with floppy discs
The musical Nerds downloads the early history of the computer age with young Steve Jobs and Bill Gates singing and hoofing their way to billions.

It's a Gabba world
Of course Yo Gabba Gabba! is a kids TV show, but we could make the case that it's more - a way of life, maybe. And with songs such as "Be Nice to Everyone" and "Just Because It's Different Doesn't Mean It's Scary" and the show's low-key surreality, the case is made. A live version goes onstage at the Tower Theater, 69th and Ludlow Streets, Upper Darby. Time: 2 and 5 p.m. Tickets: $19.50 to $46. Information: 610-352-2887 or tower-theatre.com.
