What is Caw Caw Caw?
1.
Throughout Chicagoland casinos, this is known as the legendary laugh of the "Duckman." He is known for being the comedically awful valet lead with an inept ability to spell small words or understand other basic words. He only speaks about his love of shoes.
A guest asked Duckman if he was going to get retro threes (Jordan shoes) and Duckman responded "Caw Caw Caw! I already have five of those!"
