The thing i really hate about magic... other people.

Me: Hey look, magic is real.
Jed: I don't see nothin.
Me: See? I cast a spell.
Jed: I don't see nothin.
Me: Look, i cast a spell on you, and it worked.
Jed: Prove it.

I am pretty sure that at the end of time, when God shows up to close up shop, there will be people still saying, "prove God exists".
