I have an affection for spontaneous pranks. Taking daily happenings and turning them into something "special".
One day a bulldog mix dog ambled into our firehouse only to be met by Capt Randy who took an immediate liking to the friendly slobbering dog. The dog walked all around the firehouse investigating all the nooks and crannies.
At the same time devious minds were plotting. One group set out seeking an old dried bit of excrement to be painted so as to look fresh, and then placed on Randy's bunk. I thought it needed a bit more pizazz. I took a spray bottle and wet the corner of my own bunk. When the time was right I yelled some profanities about the damn dog. Randy thought it was REAL funny until someone pointed out his bunk.
