Given that my wife and I keep knocking over any cup whose horizontal cross-sectional area decreases with increasing depth, we have heavily invested (£2 for 2) in some more mugs. One of these mugs inspires me with the slogan written across it in capitals: ADULT-ISH, partly because I feel more mature while drinking my morning coffee from it, but mostly because I can sing the word to the tune of the song "Edelweiss".
