A man comes home from work, sits in his lazyboy in front of the TV and rudely tells his wife, 'Gimme a beer before it starts.'
She gives him his beer.
About 15 minutes later, he says again, 'Gimme a beer before it starts.'
A few minutes later, he asks again for a beer.
The wife says, 'Don't you think you're drinking too much beer? It hasn't been half an hour that you got here and you've already had two beers. I'm getting fed up with this.'
The husband looks up and mumbles, 'Now it starts.'
