A politician was campaigning in a rural area.

Outside a ramshackle house, he saw a young man milking a cow. He approached the man, ready to make his pitch for a vote.

Just as he was getting started, an old man called from inside the house. "Luke, get in the house. And who is that guy you're talking to?"

"Says he's a politician, Pop," Luke said.

"In that case, you'd better bring the cow inside with you."
