After giving this topic much thought, I've decided that the most straightforward solution is as follows.
You'll need the following items:
- Jacket with Topit
- A FISM Flash
- A Universal Raven
- A stooge in the audience
Right... begin by palming six silver dollars in your right hand. Start out by doing some card manipulations (cause kids love that stuff). Make sure you show them your 'invisible' classic pass, just to check whether they catch you or not.
Next, have your stooge in the audience pretend to choke on an M&M. While everyone turns around to make sure they're OK, load the rabbit into you Topit.
When the drama at the back of the room has subsided, use the FISM flash to misdirect while you squeeze the rabbit's foot... HARD!!! I should point out that I prefer the Tenkai Pinch for this move, however this is a purely personal choice. This will cause the rabbit to jump into your awaiting hand.
Now produce the palmed silver dollars one at a time, and pretend to feed them to your rabbit, while actually disposing of them via the Raven.
This allows you to end on the delightful pun "... because we all know it costs a lot of money to feed a rabbit!"
(If this isn't to your liking you could always fork out for a black art Circus Wagon Box)
