If you really really need an April Fools joke for some reason, but don’t have a good one lined up, here’s an old favorite:
Go up to someone and tell them that Sunday is the day the clocks change, but they should be on their guard, because some unscrupulous people are taking the opportunity for an April Fools joke, and will tell them to turn their clocks forward. Remind them that it’s “Spring back, Fall forward”, and encourage them not to fall for other people’s jokes.
