A few ideas for how to spend this festive day:
1. Fill a mayonnaise jar with vanilla pudding. Walk among a crowd eating it with a large spoon.
2. Gather a set of crayons in the order of the rainbow and attach them to someone’s windscreen wipers.
3. Don a t-shirt with ‘life’ written on it, and stand on a street handing out lemons to passers-by.
