Stealing a lottery ticket?

So here's the thing. My room mate goes over to her friends apartment on the floor below us once a week to hang out. She and her friend have this weird thing were they will both purchase 3 to five scratch tickets and scratch them off together at her friend's place when they hang out wednesday nights.

She had three of the same scratch tickets attached by magnet to our refridgerator. She is out of town until tomarrow night.

We always play little pranks on each other for fun and her last one on me went a little too far, so I decided to play a slightly mean one on her. (Remember, she's out of town.)

I scratched off her scratch tickets, with the intention of just kind of hanging them back on the fridge. Well, you can imagine my suprise when one of them turned out to be worth $10,000 dollars.

Here's what I'm considering: She NEVER signs or dates the back of her tickets, and I know she buys them at the same corner store every time. So suppose I just go to that store and purchase three of the exact same scratchers, and hang them back on the fridge exactly as they would have been.

Then I go down to the lottery office first thing tomarrow and cash out the winning ticket, as if I was the one who purchased it.

And she'd never be the wiser.

Lol is there any way I could be caught? What kind of questions would the lottery office ask me, if anything?
