The one that has always stuck with me (though I've never had an

to use it) is that old Injun named SOH CAH TOA, who when doing
trigonometry could figure out the value of sine, cosine, and tangent at
the drop of a hat. Wish I could remember what those ratios were used for.

Sometimes I have wondered if roofers use Pythagoras' theorem for
figuring out how many shingles to use. Probably not, but it would
work, wouldn't it?
