Every time this thread is bumped, I watch the video again. And laugh again.
The best part are the claps and knee slaps.
Especially when they show all five of them and Brian & Dennis Wilson are slapping their legs ever so slightly off-time from eachother. You can tell whoever dubbed it, there was five of them, and they were literally going "Ok, I'll be this guy, you be that guy, you be that guy," etc.
