The ideal present for those you really can't stand - such as your boss, crabby in-laws, ex-partners and so on!
The person will be sent a Christmas Card with a huge bottom on the front festooned in holly, upon opening the card they will read the words:
"You are the lucky recipient of a FART IN A CARD!
Please smell the card for more details.
Best farting wishes from"
Obviously you have to produce your best fart to go in the card before it is sent!
So come on then - place yer orders here!
