When do you know you've been married too long?
The only reason you go down on it is because it doesn't talk back.
Last year, I bought my mother-in-law a cemetery plot as a Christmas gift.
This year I didn't buy her anything..
When my wife asked me why I didn't buy her mother a gift this year I told her "Hey, she never used the gift I bought her last year!"
And that's when the fight started...
What's the difference between a girl who spits and a girl who swallows?
A wedding ring.
My wife will buy anything marked down. Last year she bought an escalator.
