Joann and Mike Moser weren't even mad when they found out their 2-year-old son Kyle was using fingernail clippers to break into his sister's room late at night to steal a stuffed unicorn.

"Kyle has always been one to fiddle things and try to see how things works," Mini-MacGyver's mom told ABC News. "We were impressed that he found the fingernail clippers in his room, flipped them open and used those to open the door."

Kyle's impressive talent was recently caught on camera after his parents set up a sting to catch him in the act.

Joann described to Huffington Post how it all went down:

Our 8-year-old daughter came to us one night and told us our 2-year-old was taking stuff at night out of her room. We told her to ... just lock the door. A couple nights later she told us he had opened the lock on his door. We were VERY skeptical so we set up the camera in the hall to see what would happen. Sure enough within a few seconds of closing his door and locking hers he was at the door opening the lock. The rest is on the video. We could not stop laughing afterward and we let him sleep with the pillow pet that night.

Still, being the proper thing to do, Joann and Mike sat Kyle down the following day to explain why unlocking other people's doors is wrong.

"He said, ‘OK, and went about his business," Joann said. "He hasn't done it since."
