Join IHOP today until 10 p.m. for National Pancake Day and receive one complimentary short stack o' pancakes. In return for the free flapjacks, the folks at IHOP ask you to consider leaving a little something behind for Children's Miracle Network Hospitals and other designated local charities. They raised more than $2.1 million during last year's free pancake event. Since they launched the event in 2006, the restaurant has given away more than 10.1 million buttermilk pancakes. Wow.
