I’ve mastered the ability to take any idea or thought and transform it into anxiety. Jitters McGee
I can make double fart sounds by laying on my back and cupping my knee-armpits with both hands.
Not entirely useless though; I showed this to my SO 7 years ago when we started dating and she was clearly impressed as she’s still hanging around.
I was worried I was the only one! I can also do elbows, neck, and chest. Also eye sockets but it’s not very loud, I’m working on it.
