I expect a few of them were unwrapped on 25th December: the huge padded slippers shaped like fish, ducks, monsters, cats and so on. I expect some people see them as unwanted tat, but does anyone love their funny slippers?
I love them - I have several pairs, including a pair of sharks with the words "where's my dinner?". Funny slippers were popular in my uni hall of residence: even the boys wore them.
