Doh'!

Last nite i managed to lock myself out of my sim card, i put the wrong code in a few to many times, i was trying to run the battery down and it seemed like just having the error wrong code screen pop up would do it, i was just thinkin this could lock me out of my phone, so i was about to stop, and then it popped up. i'm at tafe 9-5 today so i'll call someone during the lunch break, im assuming it would be telstra i call (mobile phone on a 24month contract with them) it asks for a PUK code :S any ideas please?
note: i had a couple to drink last nite, it was warm, i barely slept all nite, and now i've been woken an hour early and cbf trying to sleep
