A man comes home from an exhausting day at work, plops down on the couch in front of the television, and tells his wife, "Get me a beer before it starts." The wife sighs and gets him a beer.
Fifteen minutes later, he says, "Get me another beer before it starts." She looks cross, but fetches another beer and slams it down next to him. He finishes that beer and a few minutes later says, "Quick, get me another beer, it's going to start any minute."
The wife is furious. She yells at him "Is that all you're going to do tonight? Drink beer and sit in front of that TV? You're nothing but a lazy, drunken, fat slob, and furthermore..."
The man sighs and says, "It's started...."
