One of my favorite April Fool's jokes was when Steve Morris turned KRTH into "The All New, All-News 101 FM" on April 1st. He and his crew spent the entire morning drive doing news and traffic, and nothing else - no music at all. It was pretty convincing.
You're right - seems no one has a sense of humor any more. I guess radio's just mirroring the general economy-driven gloom in the air.
