To be fair, it depends on what you look like as well. Most bouncers have a fair idea of who looks likely to cause a bit of crap after a few drinks and will be trying to spot them in the queue. If you look decent and just there for a laugh, unless they're overly strict, i cant see them delibitating too long over your passport. Besides, it will still display your age, as long as your pic holds relatively similar to your look you'll be fine. It has to be renewed for other situations including airports, not so much to get into clubs and eh, do other stuff.
