my fiancee's uncle used to work at DLR and back when they did b-day stickers he would give us a stack of them. we still have them some where. we used to go with a group of friends quite often and would give a b-day sticker to who ever had their b-day the closest to the day we went. only once have we received a front of the line pass. that was pretty cool.
when i went a few weeks ago though, she got me a b-day button. some CM's looked at me like i had 3 eyes or something. some said happy b-day but i think i got more happy b-days from the goths there for bat days. which is cool with me.
