He has actually rambled about birds, and it's actually pretty funny. He got off a tangent about a neighbor's peacocks in his past, then talks about how owls would take their heads off in a swoop. "But I digress..."

Unfortunately I don't quite remember the Knowledge Fight episode it's in, so I can't direct you to it. What I recall is he was talking about something completely different and god sidetracked.

Go, unreasonably buff bird!

Ahh, the majestic space duck.
