XX - Buy or rent?

I did the math on the Paul McCartney-Heather Mills divorce. After 5
years of marriage, he paid her $49 million. Assuming he banged her
every night during their 5 year relationship, it ends up costing him
$26,849 per lay, not counting attorney's fees and court costs.

On the other hand, Elliot Spitzer's call girl Kristen charges $4,000
an hour. Crazy, right?

But...

Had Paul McCartney employed Kristen for 5 years, he would've paid $7.3
million for an hour of sex every night for 5 years (a savings of $41+
million).

Value-added benefits are: a 22 year old hot babe, no begging, no
coaxing, never a headache, wide open menu, ability to put BOTH legs
around you, no bitching and complaining or "to do" lists. Best of all,
she leaves when you're done and comes back the next day ready for
another round. All at 1/7th the cost, with no legal fees.

Is it just me, or is it better to rent?
