It's quite simple. We speak of the Nativity (and, as all intelligent thinking peoples know, "Jesus is the reason for the season") which is set around a manger.

Manger, for the benefit of the un-educated I shall now translate from the original French to English, means to eat.

Hop to it!

(For the benefit of those without a sense of humour, the above is farce, a joke, parody. Put the angry mob supplies back in your shed.)
