"Before it Starts ..." joke

Santa Singh 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. ..`
Santa sighs and says, `It`s started... `
