I almost forgot (ironically) I memorised Pi to 600 digits.

I think this is the central for internet nerd-dom.

I was doing magic tricks and one of my tricks involved memorising someones phone number and getting them to pick the cards of their number etc.

One of my friends involved bet me that I couldn't do 100 digits and then just kinda kept going until I got bored :) 

Thats the nerdiest part. It was just because was a SH, not because was a good game. Sadly, it was (at least for me) the worst of them all...

I wish I could say this story is exaggerated for effect, but it is not.

I am a bigger nerd than you because...

During a job interview I explained the mechanics of an MMORPG guild, and the fact that I was GM of it and thus was "leading" over 120 people on a daily basis, as a reason why I at 19 years old would be great for a middle management job at their firm despite my only RL management experience being at a Burger King.

It's not that I explained it that makes me the bigger nerd though, its that I actually got the damn job!

I think you can add doing magic tricks to your nerd list

I am still deciding whether to actually go to my graduation or let that piece of be sent to my home so I can game with friends.

Haha true! 

I didn't include it as it was a very social thing, not like a stage or anything but wasn't exactly sat in solitude practicing sleigh of hand, that was valuable RuneScape time! 

I used to play ported Mario games on an Atari, I still own an Atari Jaguar and sent away Cereal UPCs to get Jaguar games in the mail. Oh and the ports were on 5-1/4 floppy and 3.5" Floppy disks.

Still beats sex though :P
