My fav is still that one you came up with about stupid people having a purpose..to serve as an expample lol.

That one too is not original to me. I first heard it about Galingburg, as a matter of fact.

The line goes: There's some good in everything. If nothing else, it can serve as a bad example.

Though it likely holds some truth in every field, coming up in kitchens during my youth I worked for mostly talented chefs whose personalities were geared towards training and passing on knowledge and expertise... but every now and then I'd cross paths with a stubborn, unfriendly stingey sort who seemed unwilling to take youngin's under his wing in any generous capacity. It was at those trying times when I told myself "Hang-in the Kev- while it's optimum to learn from others how TO do something... with the boogers of the lot, at least there's always the option of learning the second-best way, which is how NOT TO DO things."
