Its incredibly funny how a lot of sites these days support the Konami Code 
(Uber Geeky)
Facebook for example does some funny stuff.. & so does Google reader. (NINJAS!)
A little bit of .js does te trick And its readily available from code.google! With examples out there on the interwebs.. Ready for anyone to implement! (So just look out you dont get rickroll’d (link) 
hehe)
A list of sites supporting the code is on konamicodesites.com
