Webster's Slaughterhouse is where Ernie Krinklesac works. Cleveland Jr. tries to get a job there in "The Curious Case of Jr. Working at the Stool" but is mistaken for an escaped cow. The situation isn't improved when Cleveland Jr. is revealed to "moo" when he is scared. Webster's Slaughterhouse's logo (red W) looks like McDonald's logo (yellow M) upside-down.
