So, a man from Montana walks into his house holding a sheep under one arm.
His wife sees the sheep and screams, "Why you bringin' that filthy animal in here?"
"This is the pig I've been keeping with when I'm not with you." He replies.
"That's not a pig, it's a sheep!" She insists.
The man looks from the sheep then back to his wife and says:
"I wasn't talking to you."
