When I was a kid we had a key hidden in a fake rock in our garden. This was just in case there was bad traffic and we got home from school before our mom got home from work. Whenever it happened I would be very careful that nobody would see me pick up the rock. I would casually walk around the yard checking for neighbors walking their dogs or cars driving by. Then, when the coast was clear I would stop next to the rock and bend over to tie my shoe. I would quickly pop the key out of the rock and then untie and tie my shoe to complete the charade. I fooled every bad guy in the area with my amazing acting skills.
