Sketch comedy vets Schadenfreude celebrate their 10th anniversary by reviving material from their 1998-2001 run at the Heartland. The show's at Theater on the Lake and starts at 7:30pm. Tickets are $17.50, but can you really put a price tag on Monica Lewinsky jokes?

In other dated humor news, Mortified comes to Chicago tonight, with local authors and comedians reading diary entries, songs and other adolescent ephemera from their past. The show starts at 8pm at the Green Mill, and tickets are $10 beforehand and $15 at the door.
