I always hated April Fool's day jokes where stations would pretend to flip formats, especially top 40 stations that went back to all 1994 or something, using all the slang and everything from that generation then picked the worst songs from the generation to play. What was even worse was when the listeners couldn't even see through the blatantly fake prank!
There was one time Hot 97.5 did this "half-assed" April Fool's prank talking about flipping to country (and it was so see through that I, as a teenage kid who still thought radio could play what they wanted if they chose, knew it was a prank). A little mention here and there, then at the top of some hour, music stops, non emotional goodbye's are made, pause, then country music very briefly started playing. The whole time I was just waiting for them to say "April Fool's" and get back to their regular music.
Normally, the April Fool's pranks on Coast To Coast AM are silly, but I couldn't believe that anyone actually fell for last year's prank about them dropping Coast To Coast and flipping to Toast To Toast, a radio cooking show, because "that's where the money and ratings in radio was now". At least the Toast To Toast format cooking format with live interviews and stuff was better than a Big Foot sighting or some past dinasour-related species that managed to survived and no one knew it. I'm not sure what this year's Coast To Coast prank was.
A good April Fool's joke (mainly for radio board listeners) would've been WiLD 105.7 / 96.7 being placed on a stronger signal for a day or Q100 adding "rack city" by Tyga along with Drake's "the motto" in regular rotation and V103 adding Calvin Harris "feels so close" to hourly rotation with a half dance half booty shake 5 o clock mix. I would've done it! To make it even more interesting, lets say that all these things not only happened, but it also happened without me noticing or logging in to say anything about it! Now THAT would leave a few people thinking ??? !!!
