Yeah.....I understand it a little more now. So basically, the movie isn't really trying to be gag-funny, it's more of "now that I think about it, that scenario/event WAS funny!" type of funny....
Yeah, the more I think about the movie, the funnier it gets. Maybe it takes more than one viewing?
I think this movie was the EPITOME of "situational comedy." Just imagine yourself rocking the house, your band members erupting from alien pods on the stage, and yours not opening

That would be terrible......
.....and that's why it's funny I guess
I might have to borrow it and watch it again
