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