I'm trying to understand why it's so difficult to punch holes in bananas.

Perhaps the banana is there to keep cats away?

Patented by Mine SAFETY Company!

I believe it would have been much easier to read the narrative in the patent if it had been written my Mr. Temple himself rather than the attorney.

Must be a really tough banana. Maybe it's a GMO variety that's been engineered to not bruise in shipment.

Bet he had to shell out for the legals.

no legal worries in 42,i bet the oil field companys bought some, and the us military in ww2 and korea bought some too, never know when u might need a hole in some thing and no electric drill around either..

I wonder if with a bit of mod , this device would work with diesel or WD40
