Pranks are difficult to do right. They easily can be experienced as frustrating, aggressive or plain idiotic by the receiver while the giver thinks it's totally hilarious. It requires a lot of empathy to create a good prank that doesn't hurt anyone especially when it's experienced online, ie. without being able to interact with a "WTH man?! - Sorry, tried to prank you but it misfired. You OK?"
In the good pranks category, I'm especially fond of new product announcements when it's clear it's a joke like Amazon shipping authors directly or the Google's "Clean screen" app. They are often refreshing and witty and it's just what I want from a good joke. And it's free positive marketing if done right. (Just don't announce your company bankruptcy, like Elon Musk.)
I'm still holding to my idea of swapping a font with https://hellveticafont.com/ for a day. I'll just make sure it's not obstructive and can easily be disabled.
