It's been an interesting career trajectory for Janeane Garofalo, who over the years has parlayed her status as the comedy world's patron saint of Generation X into a role as an outspoken liberal comedian and activist. Who else has so effectively combined idealistic politicking and leftist one-liners with the deadpan delivery of a professional cynic? Put that chip on your shoulder and head down to the Wilbur Theatre (246 Tremont Street, Boston, 617.248.9700) to catch one of her stand-up shows tonight at 7:30 p.m. or 10 p.m. Tickets are $25 or $35 via ticketmaster.com, and well worth it to find out what will fly from Garofalo's sharp tongue next: she most recently garnered controversy earlier this year during an MSNBC interview, when she referred to anti-Obama Tea Party protestors as "teabagging rednecks" and equated Republicans to "white power activists." If she's willing to go there on national television, do think rednecks will be safe in a blue-state crowd? You've got to be joking.
