Marriage Is Expensive

One day, Smith asking about marriage to his father....
Smith: Dad?
Father: Yes son... (while reading newspaper)
Smith: How much does it cost you to be married with Mom?
Father: (Stop reading newspaper and staring blankly on the wall --long pause)
Smith: Dad?!
Father: I don't know son...

Smith then goes "FFFFFFUUUUUU!!!!!!!!"
