One of my Java programming assignments has the kids practicing how to create new objects and call methods on them, in this case to draw a stick figure with multicolored body parts in an applet window. Part two of the assignment asks them to modify the actual drawing routines to fill in the head oval or something similar. One guy said, "what do these numbers mean" and when I told him they were coordinates he suddenly got all animated and said, "so can we draw extra body parts?" and I said "sure, your stick figure can have extra arms or... [and at that moment I knew exactly what he was going to draw]...um, keep it clean."
He needed some help with a syntax error but didn't want me to see his code. (I assured him that this was not The Matrix and I couldn't look at his code and say "oh, that's a blonde in a red dress"...) And yes, the result was a work of art. I couldn't help laughing and telling him that, actually, "penisColor" was an excellent, descriptive name for an object property. Heh.
Whatever it takes to get these kids excited. Er... within reason. :-)
