I would have the power of internet-item-generation! I could get anything I want from the internet (on webpages) just by touching it with my pointer finger on the screen.
If you guys ever watched Code Geass when you're younger, I would wish for the mind control power Lelouch has.
I'm digging the materialization wish. If you could literally materialize and dematerialize anything or anyone you want at any time, you could have alot of fun. As long as the people you materialize are willing to do anything you want. Heather Graham's titties are gonna get a serious tongue bath if I ever gain this ability.
