One of the guys I frequently run into at my department kitchen uses one of these for his afternoon cuppa.
It always reminds me of that sequence from Annie Hall.
Annie: Sometimes I ask myself how I'd stand up under torture.
Alvy: You kiddin'? If the Gestapo would take away your Bloomingdale's charge card, you'd tell 'em everything.
He is a nice guy and all, but c'mon, coffee mug Che is ridiculous. I know this sounds too glib: it puts the moron in oxymoron ;) .
