I like the message given about taking time for yourself - relaxing, etc. I do it far too infrequently and every time I do take a real vacation I realize how badly I need to.
But to walk in with no notice and tell your employer that you're disappearing for 3 months is unprofessional and unreasonable. You work for a company which has schedules and deadlines; just as you expect them to pay you on time, they expect to have at least a little bit of warning before you up and disappear on them.
3 Months vacation - great. Presumably you expect to get it unpaid (Your employer probably gives you 2 weeks PAID vacation) and many employers with a few weeks warning would be happy to accomodate you. But to tell them "I'm leaving - see ya!" and expect to have a job waiting for you? Come on.
And if you don't bother telling your manager ahead of time - you run the very real risk of his ire and wrath...
As the trunk poster said - you can only pull this off if you are really good at what you do, and prepared for the negative consequences if they happen.
