Comedian Brett Gelman presents his one man musical opus "1000 Cats."

1000 Cats is amazing for 1000 reasons. Some of these reasons include Reason #16: Brett Gelman sings and dances while wearing tight black shorts, a black tank top, and cat ears; and Reason #137: It'll make you question your purpose on this earth; and, of course, Reason #998: It goes well with a nice glass of organic piss.
