I'm always messing with my kids. That's why they wouldn't be surprised if I did this to them. They have hidden my truck keys and then forgot where they put them.
That's my daughter's birthday. So much fun when she was little and telling her I bought her a pony... And following up with "April Fools!" By the time she was 10 she told me that it wasn't funny anymore.
"What do you mean that those aren`t black jelly beans?" or "Kids don`t eat those orange, purple, blue, and white ones!" or "You just got BEAN BOOZLED!!!". (The blue/purple/orange/white ones are Tide Pod flavored!)
