For some reason IHOP is declaring tomorrow National Pancake Day, when everybody knows that international Pancake Day (aka Shrove Tuesday, Mardi Gras, Fat Tuesday, Paczki Day, etc) was last week.

But the important thing is that mega chain is giving away free short stacks of buttermilk pancakes in exchange for donations to the Children's Miracle Network. I've never been to an IHOP (locate one here) so I can't vouch for their flapjacks. But I can get behind their lysergic 1969 television commercial. Watch it after the jump.
