i had to a few times too...the most memorable one was for woodstock. a couple friends and i had already spent money on tickets (18 bucks for the weekend) and about a month before it started i asked them premission to go with my firends telling them it's nothing more than a campout...just 800 miles away. they said no way...so 4 days before the festival i "acted up" and didn't get my haircut, as told to do and then i get the old, "well if you can't follow the rules of the house you gotto go...". i pulled their bluff and left for 2 weeks of fun and frolic at woodstock and the clean-up afterwards! then i came home and got my hair cut...
