You win the grand prize, a wigwag will be in the mail, even though the machine that uses them have been out of production almost 30 years.
True story (or at least as true as too many years of faded memory can make it). It's the time of the year the service dept manager has to do ride-alongs for performance evals. One of the outside techs was a 50-ish year old whose weekend job was Baptist preacher. Service call is to sorority house at the local university.
They, of course, have a bad wig wag assembly. But Jerry just can't make himself tell the girls this. It's spring. Some girls are in bikini, one is in a towel and others are just generally milling around. And Jerry can't tell the girls they've got a bad wig wag.
Finally I bail him out and tell the crowd what's up. The house mom asks (with a big chit eating grin) just how much a wig wag will cost. By now Jerry is 14 shades of purple and may actually have been holding his breath. I whisper in his ear (as well as one can whisper while laughing) that I can't complete his eval positively if he can't speak with the customer. So, against his own will, he tells the girls, yes, they've got a bad wig wag and it'll cost some unremembered number of dollars. Then he runs out of the house and heads to the van.
I got one phone number that day and the next morning had two other guys bidding to see who would get the return call when the parts came in.
