Did you know? That... A wet bird never flies at night.?

if you mean drenched then no bird would fly even in daytime, the ones that dive are water proofed by preening

on the other side of the wall would be a pink floyd concert with hawkwind as special guests

1.a wet bird never flies at night

"The saying 'a wet bird never flies at night' was a catch phrase used by Jackie Vernon - a stand up comic on the television in the 70's. You're probably not old enough to remember him - but he had a very dry humor and never smiled. Think he might also have been the one that said 'It's bad luck to blow-dry a wet raccoon.'"

There's no wall out there, though.
