I used to drink at a bar a lot.
But I don’t drink anymore, but I still went to the bar to have a soda now and then.
Until I overheard the bartender telling a joke to a customer that began with Two Jews walk into a bar, and the bartender says I don’t serve Jews.
I left before the punchline, called the owner, and bought the place.
The next day, I went back.
“I’ve got a joke for you,” I said. “One Jew walks into a bar. The one he bought overnight. And fired the bartender.”
That’s a punchline!
