Many years ago my Mom pulled this on the family. It has been repeated a few times.
Make pancakes for the family breakfast. The top pancake of each stake is made by taking a piece of paper towel cut to the proper size and dipped in pancake batter. This pancake will be too tough to cut through. Be sure your stake is normal and wonder why everyone else is having such a problem.
If I could spell this might make sense
stake = stack
Now, that is winner. Kids will fall that for sure!
