No doubt - boobs!
In fact I was about to get it done when I got offered the job I have now and didn't want to pass it up. (Day shift position right off the bat - couldn't pass it up)
Seriously, I had already picked out a set of beautiful 400cc silicone round implants, had held them in my hand and felt their glory. I had my financing approved (they'll finance anything, won't they?) and had already had my pre-op labs drawn.
We were shooting for surgery the first week of November, I just had to make sure I could get the time off from my previous job. My new employer called the same day I got my labs drawn to offer me the job, starting full time orientation November 1.
No boobies for me
So, we spent the money on other things, and it would really be too frivilous of an expense now. But if I came into a large sum of money tomorrow, I would do it in a heartbeat.
