Cousin Itt can swim?
It’s not that the beard, the long hair, or the shorts are necessarily bad on their own. (I like a little retro shout-out now and again.) But… Beard + long hair + 70’s gym shorts that are 2 sizes too small = bad outfit.
It’s like half ZZTop and half roller-disco. Both are fun – but I don’t think ZZTop would go to a roller disco.
