I didn't do much for April Fool's Day this year...but I did do this one little thing to John. I just stashed this under the driver side wiper blade:
It worked out perfectly since he started parking in a new spot this week. It actually panicked one of his co-workers first :)
I folded it like a card and wrote a message on the inside to tell him April Fools! It was fun and super easy.
I found this cute idea on Love, Actually.
