The husband and a wife went to bed. Their child went to bed too.
The husband offered his wife to make love.
She asks to wait till the child is asleep.
After some time the husband asks again, but the wife thinks that the child is not sleeping yet.
The angry husband went to the kitchen and sees the bottle of champagne in the sideboard.
He takes it and opens it with a shot and drinks shampagne with pleasure.
The son hears the shot, rans to the mother and says:
"Well, you see what has happened because of you! Our father shot himself!":)
