But, what about the Alcoholic Bums?

This might offend someone but know I have the utmost respect and love for the homeless and it’s called a joke.

Mack: We should see if we can track down some vodka tonight.
Me: Heh.
Mack: Why the snicker?
Me: Nothing… you alcoholic.
Mack: What?
Me: Nothing! I was joking.
Mack: You bum!
Me: Why do you call me a bum? (pauses) Oh wait cause I have no job! (cracks up).
Mack: You said it, not me.
