Already an astoundingly good time, improv comedy is even more hilarious when there's a competitive aspect. In "Cats vs. Dogs: Battle of the Beasts", two of iO Chicago's best teams compete each week to prove which animal truly is superior. Will Law Dog and Ms. Mistofolees emerge victorious? Find out, and then go back again the following week, when the same teams compete again in a completely different show. That's the magic of improv at Del Close Theater.
