Magic Trick

So my friend got into this thing called Boy's State where several students are selected from each school to go to a university and participate in a student government program. Here's a story that he told me when he came back:
>At lunch period
>Everyone talking getting to know each other
>One guy says he knows how to do magic tricks
>Everyone intrigued and ask for demonstration
>He asks for a $1 bill
>After getting the bill he has someone write down the serial number on the bill
>Really weird that that matters but whatever
>Says he's gonna make the bill disappear
>He grabs it tight and moves his hands quickly and rips the dollar bill in half
>Everyone looks at it, it's legitimately ripped in half
>Guy who owned the dollar bill is pissed
>He apologizes, says he's clearly not on his game
> ************* .jpg
>He gets up to get food
>All of us pissed and talk about how ******** that was
>He comes back with an orange and starts to cut it in half
>No one's paying any attention to him
>He looks up and says "You know I always liked oranges, they're such magical fruits"
>Pulls out in-tact dollar bill
>Serial number is the same as the dollar bill that was ripped in half
>We still have the ripped in half dollar bill
What the **** he duplicated the bill somehow or some **** it is the same ******* dollar bill counterfeiters take note
