The Pigeon is often the subject referenced in the saying "Arguing with an idiot is like playing
chess with a pigeon, no matter what you say, they will knock over the pieces, crap on the board, and strut around like they've won."

Earth has been proven
time and
time again to be false, yet these Pigeons keep promoting the belief"
"I was arguing with this Pigeon earlier, it was like talking to a wall."
