If you thought festive roller-skating was eccentric, try this for size. Tió de Nadal, which translates as the Christmas log, is a Catalonian tradition whereby a smiling face is painted on the end of a hollow branch. During advent, children are charged with looking after the log, giving it sweets, fruit and treats to ‘eat’ every night and keeping it warm with a blanket. On Christmas Day, the log is placed by the fire and beaten with sticks while the children sing the Caga tió song, whose rather crude translation is best left to your imagination. The tió obligingly defecates sweets, nuts and dried figs, depositing them under its blanket. When it has ‘done its business’ it lets you know it has finished by dropping a salted herring, a clove of garlic or even a puddle of water. The ‘poops’ are then shared between the children.
