Can you help me find my forks?

My neighbors play jokes on each other. One day one neighbor (Jeff) went into the house of another (Tom) and loosened all the light bulbs. Tom retaliated by planting corn in the flower beds. Water hoses have knots in them and sometimes lawn furniture is "rearranged".

I took inspiration from them and one day smeared a happy face on the windshield of my friend Sam's car. I did it with a frosted cupcake. It looked really cute. I didn't tell him it was me that did it, but he found out. Now all my salad forks are missing. He says he didn't take them. I don't think he'd be that creative, so I'm wondering if he had help from somebody else.?

Anyway, I need a new practical joke that I can play on him. I was thinking of wrapping his car in plastic wrap or aluminum foil. I need some suggestions and I will update as the battle escalates.
