April Fools' Day Joke?

[mysid]

For the last few years, I've pulled some sort of April Fools' Day joke on my three kids. Last year I short-sheeted their beds. Their favorite was the year that I served them meatloaf and mashed potatoes for dinner. The meatloaf was actually a loaf of rice crispy treats made of Cocoa Rice Crispies, and the potatoes were actually vanilla ice cream with a yellow Starburst as a pat of butter.

They are already looking forward to this year's joke. The problem is, I haven't thought of one yet. Any suggestions?
