Hahaha. I'm so not laughing AT you, but this reminds me of a terrible (But hilarious!) April Fool's Joke that my cousin used to play on my aunt and uncle EVERY year...
He's now moved out, but EVERY (and I mean EVERY) April 1st, he'd change the salt and sugar... So, every morning on April 1st, they'd put 'sugar' in their coffee, stir it up really good, and then drink it... OMG He used to get in SO much trouble, but they fell for it every time... They never paid attention to the date. ;) Haha. Those were the days. :D
That's why I don't like the first of April. And because I dislike it so much I'm always aware of the date. I wonder how after years of that joke your aunt and uncle still didn't remember. Ah, the precious coffee!
