A cowboy, fresh from Texas, strolls into a bar in Montana and orders three mugs of Bud.

A cowboy in Montana orders three beers and sips them one by one in rotation. The bartender says, “Beer goes flat—why not order one at a time?”
The cowboy smiles: “I’ve got two brothers in other states. We promised whenever we drink, we’d have one for each other.”
He does this for weeks… until one day he orders only two. The bar goes silent. The bartender whispers, “I’m sorry for your loss.”
The cowboy laughs: “Nobody died! I just joined the Baptist church, so I quit drinking… but my brothers didn’t!”
