the ability to come up with more of these!
The ability to quadruple post! [sub]sorry...[/sub]
The ability to talk to animals! Provided said animals speak English (maybe French). And aren't annoying.
Also the ability to turn invisible, but only whilst playing the trombone and holding a neon sign that reads "I'm invisible. Kick me"
Finally, and most spectacularly of all, I have the ability to actually read Twilight! (only half of the book to go, and it's not quite as bad as I've been led to believe. The writing's terrible, and the characters are all either stereotypes or spectacularly bland, but the story-line's not total crap. Possibly because nothing's really happened yet. This might be a job for a user review after I've finished)
