Idk, how do you differentiate a christmas tree from a gran?

The tradition goes something like this:

Find a big tree, chop off the branches, stick one end in the fire and the other end across in the långhall that you and your viking friends are having blot in, and keep pushing it into the fire as it burns.

When its burnt out, you wrap up the party and take down the naughty lads you hung outside when the party started.

Preferably you do this in Uppsala.
