Boom-goes-the-dynamite by Aaron & Alli
As an insensitive pre-teen brat, I concealed my Casio digital watch under my grandpa's bed, and set the alarm to go off in ten minutes. I knew he would go up for his afternoon sleep in five minutes. As he lay down, I "chanced" into his room, and narrated to him in calm undertones about how we'd learned about explosive chemicals in Chemistry class that day. Then, I let it slip, by accident, that we - the boys - had gone ahead to devise crude time bombs. Then, in passing, I mentioned that I'd stowed my bomb away under his bed for safekeeping. Eighty-three years of human experience doubted me until I started flying from the room three seconds before the alarm went off. Bless his soul, (and may he continue to rest in heavenly peace) my grandpa shot past me, and bounded down the stairs! It was the quickest I ever saw him move! He was not angry or anything at all. He called me naughty, and patted me on the back. Gee, I loved that prank!
