Of course, anything as popular as the Trapper Keeper will almost inevitably face a backlash—but in this case, the backlash didn’t come from students. Crutchfield remembers that some teachers complained about the multiplication and conversion tables, which they said could help students cheat. “It was a controversy at one time,” he says. “One teacher said, ‘Hell, we can take the portfolios away from them while they’re doing their tests.’ Most of the teachers were very honest and said, ‘Anything that helps me pound it in their head is good.’”
Hilarious piece! I remember Trapper Keepers fondly from my childhood, though I don’t think I ever actually owned one.
