Two-Story House

A man appears before a judge one day, asking for a divorce.
The judge quietly reviews some papers and then says:

- Please tell me why you are seeking a divorce.

- Because - the man says:

- I live in a two-story house.

The Judge replies:

- What kind of a reason is that?

What is the big deal about a two-story house?

The man answers:

- Well Judge, one story is 'I have a headache' and the other story is 'It's that time of the month.'
