In this thread I asked about Christmas crackers. These are things I know about, and have participated in using at Christmas parties.
But what about Boxing Day? I know that it is the day after Christmas, and I’ve read the definition in the dictionary; but what do you do on Boxing Day?
Q: Why do geeks not know the difference between Halloween and Boxing Day?
A: Because 31(hex) = 25(dec)
You messed up a good gag -
that’s 31(oct) = 25(dec)
On Boxing Day, you sleep off the effect of Christmas dinner. Also, you play with your new toys, and go to Boxing Day sales.
That’s about it, really.
That, and sing Boxing Day carols… 
If you’re the lord of the manor you box up your leftovers and have them delivered to your poor but devoted retainers. Otherwise you might go to Matlock Bath and throw eggs and flour at people on homemade rafts.
Fortunatly, The Great Escape is usually on the telly
It is also called " St. Michael’s Day " because that is when you take that crappy sweater ,that your aunt bought you ,back to Marks and Spencer and get a refund.
As well as the activities mentioned Boxing Day is now associated with sport. There are many horse-race meetings as well as a full programme of football . Also ( although I am loath to mention it ) most of the fox-hunting packs meet and ride on this day.
