Boldewyn is the name of the donkey in German fables (at least, the ones from Goethe). Despite its bad name, a donkey is an animal with its own head and quite a portion of wit.
As someone pointed out once, if you say to a horse to jump down that abyss, it would happily do so, whereas the donkey would give you a kick where you deserve it to.
And someone else pointed out, that laziness is a core requirement for a good developer...
