Christmas

Christmas is one of the most important festivals in the calendar, and remains devoutly pagan despite popular complaints that it is becoming a little bit too Christianised.
It is both the winter solstice (a fizzy drink) and the anniversary of the birth of political activist, preacher and Radio 4 Garden Time regular Jesus Christ, in an inn in inner Innsbruck in 0AD.

Christmas is a time when families get together and fall asleep in chairs. People also give one another presents of socks and CDs, or sometimes a combination of the two, like a sock with a CD in it.
If your Birthday is on Christmas Day, the two cancel each other out and you get nothing. This is why Jesus didn't have many possessions.
