Interesting pre-nuptial

Hey I thought pre-nuptials deal with what you do if you get divorced, but this Florida couple did one which includes:

* He will do backrubs on her three times a week for five minutes each
* she promises to cook breakfast a minimum of three times during the weekdays, and once on the weekends
* he will not wake her up on her ‘off days’
* If she uses the “F” word, she is sentenced one hour of yard work
* He has to pay $5 each time he complained, nagged or made “a fuss about her expenditures …”

What else should one include in a pre-nuptial?
