My number two son used to take a razor blade and carefully cut about three quarters of the way around the bottom of my 7-11 coffee cups and when I would get a refill of coffee as I was going to work, the bottom would give way and scatter me and anyone else in the immediate area! My family loves pranks!!
Yep, we all have that draw in the house that's filled with old wires, AC adapters, cables, 2 and 3-way connectors for the old cable box and the new, the old dvd player, the Blu-ray player, the digital camera, the computer both new and old ones that have been long since tossed away..lol..
And my little shit heads know how much I hate to be cold, so naturally they would hurl ice water over the top of the shower curtain to hear me howl!!
