Of course, there's a story behind that.
Back in the Seventies, Grandpa Joe found a deal on electrical tape. He took advantage of a very good price, something like a nickel a roll as I recall, and bought (I am not making this up) 6,000 rolls. That's a lot of electrical tape. The marked price on the rolls was 79 cents apiece by the way, so it was indeed a fantastic price.
To be fair and right by Joe, it wasn't really a bad idea. He rented arc welders, which meant he had miles of inch thick, rubber insulated welding cable which required maintenance and repair. I worked for him at the time, and believe me taping the cables where they were worn, cut, or spliced was an ongoing chore. Still, 6,000 rolls seemed an insane amount in 1975.
The welding rental part of our family business has long since ended. We used many rolls of that tape, sold some along the way to our plumbing customers, gave some away, took some home, and still use what's left for the occasional power cord repair on the drain snakes we now sell and service. After a solid forty year run, we are down to our last nine rolls.
And I am giving my kids one roll each this Christmas as one last gift from their great grandfather. I think Joe's getting a big kick out the idea too.
