Best gift for a photographer

My sister in law got me the best Christmas gift a photographer can get (non-gear related). It's a coffee mug that looks like a lens. Very much so that if I'm in a hurry I can grab this one by accident instead of a real lens. I just need to keep the lid/lenscap off to not confuse the two. Thankfully I don't drink coffee when shooting, so such confusion is not very likely. Cheers!
