In addition to 401k, my company offers a stock purchase program that is pretty sweet- you get 15% off the lowest price each quarter and can cash it after a year. If something like that is available go for it.
I straight out bought a couple really low priced houses for rentals, and that has been a good path for me so far... I still have some extra scratch so I am contemplating picking up another and financing part of it (cant afford to pay cash on all of it at the moment) and wind up with a mortgage in the 400s and rent for 8 or 9... the payoff will be swift and then I am sitting on an asset for when retirement comes.
If none of the advice so far is appealing- open a strip club. You might not make money, but the perks would be great.
