In case you didn’t know, Theatre 99 is much more than your local improv theater. Even outside of the Charleston Comedy Festival, they’ve been bringing in a steady stream of big names like Aziz Ansari, Red Bastard, and now Colin Quinn, formerly an SNL cast member and host of Comedy Central’s Tough Crowd with Colin Quinn.

This October he’ll be stopping at the 99 on his 13 Original Colonies tour to perform his show Unconstitutional, which covers some of the U.S.’s greatest — or worst — constitutional calamities since the country’s founding. You’ve got two chances to see him on Oct. 21, at 7 p.m. and 9:30 p.m. Tickets are $29 and on sale at theatre99.com.
