(LAUGHS) Halloween isn't really about being scared. Halloween is about being ridiculous and wearing hilarious costumes. Todd Barry is totally ridiculous, and if you wear a really funny costume to his show he might make fun of you in his trademark deadpan. Barry is the funniest member of comedy trio Tinkle, but only the second most famous. As an audience member, it will be your duty to bring this up. (Triple Door, 216 Union St, www.thetripledoor.net. 7 pm all-ages show and 10 pm 21+ show, $12.50 adv/$15 DOS.)
