The Good: Secondborn tried to put on my glasses. This was funny. They're about twice the size of his face. This was also basically harmless, as he managed it without breaking anything or even bending the frames.
The Bad: His idea of "put on Daddy's glasses" involves grabbing them by the lenses and wrestling them into place. So, y'know, fingerprints. Everywhere.
The Ugly: Secondborn had just finished eating a large meal of Honey-Seared Chicken. So there weren't just fingerprints on the lenses, there were great, slimy, sticky fingerprints on the lenses.
I have to applaud his effort, really. I mean, most kids are naturally messy, but this was a whole new level of "smeared beyond any possible use." Fortunately, I don't actually require my glasses in order to drive. And it wasn't terribly hard to clean, once I got to the cleaning supplies. And it was entirely too cute to be annoying.
