I've got one:
First the magician chooses a male volunteer with an obvious female partner and brings him up to the stage.
Magician: Hi, whats your name?
Magician: John how are ya', I'm going to try and read your mind, OK?
Spectator: Uhh, sure I guess.
Magician: Ok, now, concentrate on relaxation, concentra.........*snoring sound*
Magician: *waking up from snoring noise* Oh, sorry, umm, where were we? Oh yes, now concentrate on relaxation, what is your girlfriend's name?
Magician: Oh, well then who is Anny?
Magician: Ok sorry, now, concentrate on your greatest fantasy.
Magician: Oh, umm, dammit, get Anny out of your head will ya'!
Magician: *Pulls out a deck of cards* Alright sir, I want you to choose a card for me, well, for you I mean.
Spectator: Ok, that one.
Magician: Alright grab it out look at it, show it to the audience. *spectator does so*
Magician: Ok, put it into the deck, not all the way though. *he puts it in half way* Ok good, *magician grabs the card out and puts it on the top of the deck*
Spectator: Hey wait a minute now.
Magician: WHAT!? It saves time doesn't it?
That's half of what I went through the other day, it was hilarious!
