Granted. But you can only fly while blindfolded.
I wish i could fight the Naughty Sorceress.
+2 Internets to whoever gets the reference
Grated but the sorceress turns out to be your mother and she seduces you and you can't resist because she's a sorceress, that's their thing. She gets pregnant (yeah, incest, shame on you) so you marry her. A mad warlock kills you and your mother/wife but only manages to hurt your child. The child now lives in a small shoe closet under a staircase with an fat abusive uncle and jealous muggle aunt with their spoiled fat son.
I wish I had some nail clippers right now to cut my toe nails.
Granted, but since you waited so long before asking, the state of you toenails are in such a dire shape that I'm afraid I have to surgically remove them with this high precision chain saw instead. Don't worry, it won't hurt... much.
I wish I had a Star Wars costume.
You do... for Jar Jar Binks.
I wish I could meet John or Hank.
Granted, but an evil witch has enchanted you so that all you can do is make fun of:
If John == his books
If Hank == environmentalists.
I wish I could co-author a book with John.
Granted, but everyone HATES it! And you never write again...
I wish I could meet the 9th Dr and Rose, get the two of them together, help the TARDIS make Rose a Time Lady, (and all that's permanent), meet Captain Jack Harkness, kiss Captain Jack Harkness, and... stay with one of the two groups (the Captain or the Doctor and Rose) forever -- as a friend (or, in the Captain's case, more!)!
(TRY AND CORRUPT THAT!)
Easy. You make about as good of a companion as the guy with the brain gate in his head, except now the Doctor can't get rid of you. He has to put up with you for all eternity, driving him to madness and corrupting him into the Valeyard. Nice job breaking it, hero.
I wish I were like Dale Cooper.
Granted, you're so healthy that you live forever and get to see everyone you know and love die.
I wish my room would always stay clean.
Granted, but this is done by removing everything in yuor room from existence and turning it into an airlocked vaccum.
I wish to know everything.
