SNL SKIT! i dont know what its called or where to find it!?

There was this one SNL skit, and i think amy adams was the host, where there were these girls in a bar (poehler, wig, wilson, etc) and they just got up and did a random dance to umbrella and then to some tom petty song. can anyone tell me what it is called or give me the link to watch it? thanx!
