Was in the same situation some time ago with exactly $20k cash in bank account.
I invested in my new venture - developing prototype, incorporating, renting room in Bay Area etc.
Not sure that it can be good for everyone but at least it was good decision for me
Other crazy ideas:
1) Buy new chevy camaro for 25k - cmn you are in twenties that will not last long!
2) Vacation in places like Thailand can be really cheap and amazingly refreshing!
3) Taking time for self-education and trying out some of your crazy ideas!
4) Getting some more money and buying entry home around the place you always wanted to live in.
