FM broadcasting

"I don't know about you, it's just too hot today, isn't it? And it's going to get even worse. Temperatures in the mid-30's Celsius...that's the mid-90s Fahrenheit, tomorrow, maybe even hitting 100. So, please, remember to cover up and stay cool...with the hottest hits on your FM dial."

- Jim McGuffin

FM broadcasting is a broadcast technology pioneered by Edwin Howard Armstrong that uses frequency modulation (FM) to provide high-fidelity sound over broadcast radio.

In 1995 Jim McGuffin said to cool down with the hottest hits on the FM dial.
