A few lucky members of my lab received personalised mugs with chibi caricatures of them on special occasions.
Each mug has an RPG game profile which includes a catchphrase and various attributes. High INT is a given since we are all neuroscientists, haha. The images on the mugs were inspired by real events (silly ones, of course) that occurred during my time in the lab.
