All Fool's Day.
This is probably my least favorite "holiday" of the year. Why? I suppose I am a sort of a killjoy, and I would rather have a bit more sincerity and truth than more mocking evasion of integrity and face-value. Yeah, call me grumpy, if you will, but that's just how I see it.
Nevertheless, I wish you a happy Fool's day, however you wish to see it.
