A pair of Siamese-twin bears walk in to a gun shop. The bear on the left says, "The woods are getting too dangerous these days, I'd like to buy a gun"
"I can't let you buy a gun," says the shop keeper, "but I'd be happy to sell one to your brother."
"Why can he buy a gun and I can't!" yells the left twin.
The man behind the counter says plainly, "Because he has the right two bear arms."
