Where's the spud?
One of the gifts my 4-year-old son got from his Uncle Ben was a thing called a Spud Shooter. You inject the end of the gun into a potato, kind of like a syringe, and pull out a small, long section of potato. Then you shoot the piece of potato to parts unknown -- or at Dad. (Perhaps this is what Uncle Ben, my younger brother, was thinking of).
Anyway, the gun is pretty small, and it's packaged tightly in plastic and full of reminders to not aim at people, animals or your own eye. (Yep, you'll shoot your eye out, Ralphie!).
But here's the best note on the package:
Requires potato (not included).
Just in case anyone thought there was a pea-sized potato hidden behind the spud shooter.
