It's not often that a charity ad gives you an opportunity to laugh, but Save the Children is taking a humorous approach to promoting its Christmas Jumper day in the U.K. this year (on which people are encouraged to wear a festive sweater on December 14 and donate to the charity). 

An ad created by Adam&Eve/DDB imagines scenarios in which it would be ridiculous, if not downright foolhardy, to wear a Christmas jumper. There's a fitness instructor taking a sweaty spin class in an angora-type number, a dentist freaking out her patient with a huge snowman's carrot nose pointing in his face, a rapper trying to record a serious track with a Christmas tree sweater that starts playing "We wish you a merry Christmas," and a policeman on a stakeout in a dark garage whose garment suddenly lights up with the words "Ho, ho, ho." 

"Save the Children’s Christmas Jumper Day is back,’ says the voiceover. ‘Please wear responsibly.’

Jeff Low of Biscuit directed the spot, which is distinctly funnier than most of the Christmas efforts we've seen so far.
