Two men walk into a store
Guy1: Hey, watch this....
He proceeds to take 3 chocolate bars from the counter while the cashier looks away.
They then both step out of the store
Guy1: Trust me, you're never gonna see a better display of shoplifting than that. I stole three fucking chocolate bars, and they didn't even see me. Top that!
Guy2: Observe.
They step back into the store, and Guy 2 steps up to the cashier.
Guy2: You wanna see some magic?
Cashier: Sure!
Guy2: Give me a chocolate bar.
Cashier gives him the chocolate bar, and Guy2 proceeds to eat it.
Guy2: Give me another one...
He eats the second chocolate bar, and repeats the process a third time.
Cashier: Okay, so you ate three of my chocolate bars? Where the fuck is the magic?
Guy2: See this fine gentleman over here? Check his pockets.
