BOB2, your post on pranks reminds me of a story a childhood friend recently told me about his experience with a firetruck. He was very young and playing outside on the sidewalk when an older kid approached asking him if he would like to see a firetruck, the young fella said, "Yes I would". The older kid pulled on the pole mounted fire alarm, told my friend to stay put and he will see a firetruck, with the stage set the miscreant took off.
The youngster patiently waited until sure enough the firetruck appeared. After a little chat with the smiling boy a fireman escorted him home to mother.
