Pi
I was inspired to memorize pi out to 58 decimal places. This wasn't particularly difficult, because I had already memorized it to 53 places. I would like to reach 100 places, but I haven't really applied myself to memorizing pi since I was in high school.
I used to have some more geek talents, but I've stopped counting in binary on my fingers since I got wrist injuries. I used to be able to reach 32 (all combinations of five bits) in five seconds, but last of practice has pushed that out around seven or eight seconds nowadays.
While I was still keeping up my diary on Advogato, I was also practicing doing the Towers of Hanoi with everyday objects (since I unfortunately don't have a nice 64-disc set wherewith to hasten the end of the material universe, or, indeed, any nice Towers of Hanoi set). In January of this year I set my personal records:
Towers of Hanoi: 6 objects in 55 seconds. 7 objects in 121 seconds. (I really want to shave a second off of that.) You see my list of potential geek party stunts is fast expanding. In theory, if I didn't have to look, I could be a lot faster.
My original geek party stunt concept was memorizing the Nicene Creed and the MIT License and reciting them to show that they are almost exactly the same length. However, I have yet to memorize the MIT License. I do know some fairly long passages from the GNU GPL.
