Jonas Brothers & Alec Baldwin's SNL Skit

The Jonas Brothers get silly with JJ and JJJ coasters while filming their MTV special, The Jonas Brothers Experience, airing Monday, February 23 @ 6PM ET/PT. Yes, they did cause an earthquake while filming at 30 Rock.

Last night, Kevin, Joe and Nick acted in a few sketches and performed two of their hit songs on Saturday Night Live — “Video Girl” and “Tonight”

Check out “The Fourth Jonas” sketch below, where they poke fun at their own purity rings and shoot down the idea of forming a new musical group called “The Donut Brothers.”

Be sure to check out the other SNL sketch questioning how old the JoBros really are. Mullet mania!
