I have a black one adorned, in flashy gold script, with the shameless lie "Watford FC - Simply the Best!". That has survived about 30 years and countless house moves. Another of my favourites was a beautiful ornate "Victory to the Miners!" mug, which was only rarely brought out to serve tea to visiting senior managers to our Euston railway ops control office. Unfortunately dropped and smashed in the early 90s. We gave our eldest, Aethelred the Unready, a mug from Lidl for Xmas that changes colour when you put hot water in it. He loves it and it's the only one he uses. What receptacles hold a special fond affection in YOUR life? Eh?
