Comedians in Seattle do much of their grunt work in the basement of a bar in Pioneer Square at the legendary Comedy Underground. We pay tribute to our home with this open mic night (that happens every Sunday anyway) featuring Saba from Blue Scholars and The Stranger's Charles Mudede, David Schmader, and Cienna Madrid. Showgirls and "pregnant sex" may be discussed. Open to public: Sign up at 7:30 p.m. (Comedy Underground, 222 S Main St, 628-0303. 8:30 pm, $6, all ages.)
