Don't even ask. I even annoy myself with it.
We decided on these graphic print mugs from Crate and Barrel (big surprise, I know). They huge (13.5 ounces), made of porcelain (one of my requirements), cheap ($3.95 each) and they come in various, graphic black and white prints (we got two of each).
How perfect is that?
I will also tell you that in addition to his many charms, The Boy has a strict policy of being brutally honest when he hates something house related but otherwise taking an 'anything you want, honey' approach. Which I find perfectly acceptable....
