So I'm sure nobody's ever heard this premise for a joke before, but here goes. So a guy walks into a bar and sits down next to an old barfly. The barfly looks at him and says, "I slept with for mother last night, and I'm gonna do it again tonight." The guy figures the barfly is just drunk and he ignores him. The barfly reiterates his stance on sleeping with the mans mother, and the man gets up and moves to the other end of the bar. About ten minutes later, the old barfly gets up, staggers over to the man, and in a loud, slurred voice says, " I'ma gonna run yer momma ragged tonight, whaddoya think bout that boy?" The man turns to the barfly and says, "Dad, your drunk, go home."
