Great Idea for Lost and Found

Sad news, I think I may have lost my wallet today. I think it fell out of my pocket when I was biking to class this morning. I put in a lost wallet report into the segundo area service desk, on-campus police department, and the memorial union. Even I would turn in a wallet if I found it on the ground. I'm figuring there is like a 98% chance that someone turns it in because all they would have to do is pick it up on the bike path then drop it off at any building on campus.

The reason for this post is that I had a really great idea at lunch today. When I get a girlfriend, I'm planning on doing this. My girl would take my own wallet and bring it to the information desk in the memorial union and said that she found the wallet and would like to put it in the lost and found. Then when she's in the middle of a report, I'll come up to the desk looking really frantic and ask if anyone had turned in a wallet today to the person working. Then I'll look at my girlfriend who's turning in my wallet to the lost and found, and start making out with her for a good ten seconds.

Isn't that a really good idea for a prank or whatever on the person working behind the desk? I think it's a brilliant plot.
