Reggie Watts isn’t exactly a comedian. He doesn’t tell jokes or stories or anything like that. He’s more a song-and-dance man who uses his voice, a microphone, pedals, and a multitrack looper to build beat-boxed tracks like “Fuck Shit Stack,” a complex, wordy, lewd tune that toys with English grammar and commercial hip-hop clichés. Many followers of the comedy and music underground have praised Watts’ genius, but film, television, and recordings aren’t the right vessels for his art. He thrives onstage, which is probably why Conan O’Brien asked him to be his opening act for the duration of O’Brien’s Legally Prohibited From Being Funny on Television Tour. Watts’ four-night stint at Woolly Mammoth is a golden opportunity for the uninitiated to discover what fans of unconventional comedy have been loving for years.

Reggie Watts performs at 8 p.m. tonight through Thursday and 8 p.m. and 10 p.m. Friday at Woolly Mammoth Theatre, 641 D St. NW. $35–$45.
