A good way to spend a Friday afternoon is at the Whitney. Not sure when, but at some time instead of hefty admission price you can pay whatever you want. Fridays they are open until 9 PM. Right now, there is a great exhibit by Jeff Koons. Included with your just about free price is an audio tour and even museum tours if you hit it on the right time.
Many of the museums have pay what you want nights. The Craft Museum on Columbus Circle has this on Thursday and Friday evenings, the MOMA has Target Fridays. Many participate in Bank Of America weekends. Just get a credit card and then cancel if you don't want to use it but keep the card to get into museums free. Also, check before paying as city museums have only a suggested admission. You can pay anything you want. Save the $25 for lunch.
