Yo, you got jokes Son?

So a man walks into a bar.
It's the bar that I work behind...

Deadpan speech, orders a coffee, and asks if I'd like to hear a bad joke.
"Why not?"

"What do you call a Christian on a Viagra?"
he waits for me to say something, so I shrug.
"A firm believer."
Deadpan.

"Alright, how about another one? I told you they were bad."
"Yeah bro, I'm sure it'll be interesting."

"Why don't lesbians go on diets?"
"I don't know..."
"Because you can't eat Jenny Craig with Mary Kay on your face."

And I laugh and laugh.
I don't even know why but I do.
His tight black jeans, slicked back hair, horrible glasses, leather jacket.
And that voice.
It's not a Southern accent like you think Southern...it's an accent like "tacko."
So.

Why don't lesbians go on diets?
