yeah he has done that sometimes. Like when he was talking about atrazine pesticide runoff in the water making the frogs unable to distinguish sex pheromones and "turning the frogs gay" leading to the frogs dying off in ponds all over near farms.

They started going after him saying he was promoting hatred toward gay people or some nonsense, but the original clip of him yelling "they're turning the frikin frogs gay" went viral and he got a lot more hits. So he dressed up in a frog costume and did a bit where he is hopping around his studio acting like a gay frog drinking atrazine.

I dont know if people are so stupid they cant tell when someone is being serious vs when someone is fooling around, or if its a weird psychological game they play where they pretend they can't tell the difference.
