In high school we had a secret santa thing for 5 bucks max. I drew a guy named Jaime. The next day, I skipped school and looked up Jaime's last name in the phone book. Being in a small town, there were only 3 entries. The second one I tried was his mom. I explained my situation and later that day I went over to his house.
His mom answered the door and took me to his room. She pointed out his favourite hat, a bluejays baseball cap. I took it, thanked her and went home. She promised to play along and claim she hadn't seen the hat when he would ask.
On the gift exchange day, I gave him his hat back, wrapped in newspaper with a 5 dollar bill. It was a huge hit.
