Go to Party City. They have plenty of things for "40"th birthday parties.
I would get a small group of friends together and attempt to recreate the movie "The Hangover."
An ****, before you are too old to enjoy one!
A spa package in Vegas. Look for a masseur named Lars.

An "I'm not 40 yet" party several weeks or a month before......I did that for my 30th, and it was a great way to have a fun party, get presents, but not focus on how old you were...lol
