Aside from the fact, it's National Pancake Day - meaning free flapjacks at IHOP! Ever wondered why today is really called 'Fat Tuesday'? Thanks to M, here's the answer:
Mardi Gras literally means "Fat Tuesday" in French. The name comes from the tradition of slaughtering and feasting upon a fattened calf on the last day of Carnival. The day is also known as Shrove Tuesday (from "to shrive," or hear confessions), Pancake Tuesday and fetter Dienstag. The custom of making pancakes comes from the need to use up fat, eggs and dairy before the fasting and abstinence of Lent begins.
