The Coach

Okay, Ice_wallo_come, let's break this down for your tiny brain. You see, the joke plays on the idea of a coach leading a team, and it assumes the "black men" are a team, like in basketball. The humor is in the subtle racism, because it uses a stereotype and puts a white man in a position of authority over them. You are likely amused by this. You think it's clever, but it's really just lazy and unimaginative.
