Since he was looking forward to it, I wanted to do something funny for him too. So I made Koolaid. Or was it Jello?
After I'd tucked the kids in on March 31st, I made a package of green jello (just happened to be what I had on hand), and instead of pouring it into dishes, I poured it into a cup and stuck it into the fridge.
Then in the morning, I pulled it out and asked if anyone wanted to have a drink of my 'Koolaid.' That is a rare treat around here, so they jumped at it. But when they tipped the cup, of course nothing came out.
