Keenan Cahill, a 15-going-on-5-year-old from the Chicago area, has something of a cult following on YouTube, where he lip syncs to pop songs. That's basically it.

His first viral "hit" involved him choking on a cookie awhile back, but he REALLY hit it big when he "covered" Katy Perry's "Teenage Dream." It was his break.

Now a full-fledged online hit, Keenan Cahill "performed" on Chelsea Lately, doing his thing to "Down on Me" by Jeremith. Wait'll you see who makes a cameo ...
