One time I was in Mexico with my wife while our daughter was still a baby and the lady at the front desk of the hotel where we were staying offered us a crib we could borrow. It was a kind gesture, but I was a little concerned because the crib seemed wobbly. I realized there were some screws loose but though I had a multitool on me, the holes were stripped.

So later, I was talking with a local and he's like "I can fix that." He comes over and pulls a pack of toothpicks out of his pocket. He sticks one into each hole and breaks it off so that it's not sticking out anymore. Then he drives the screw back in. I shook the crib after that and it was rock solid!

Now I always keep some toothpicks handy. Fast-forward to just this year. My daughter is now an adult living in a condo, and was complaining the screw popped out of a kitchen cabinet door when her roommate yanked on it too hard. "I can fix that."
