Freshman year in high school, I was in a sophomore level math class. So last day of school before winter break, and the teacher walks up to the overhead projector, turns it on, and puts a picture of part of that picture, the "trichotometric indicator support" part on the overhead, and says:
"Whoever can build me an exact physical representation of this out of wood over break gets an automatic A next semester."
Almost all the kids started to quickly draw it down until they realized it was a joke. Took a few of the "smart" kids a little too long!
