Funny Fleetwood Mac Moment (Even if You're Not a Fan)

Forgive my lack of substance, but I just wanted to share because I think this is incredible -- not the song itself (although that is too), but what happens during the song. If you're impatient, fast forward to 4:30. Then watch the very end, after the song ends (5:54). HILARIOUS. After seeing this, are there any lingering questions as to whether or not Stevie Nicks and Fleetwood Mac are a true class act? No, I didn't think so.
