Back in high school I used to listen to Mr. KFI on the radio. He ran a show with no guests, no topics, and no screeners. It was hilarious.
Since then he has switched stations and become Mr. KABC. Same format, different station.
If you want to hear something totally funny, listen to Charlie Hero, a bit in which Mr. KABC has asked his listeners to call in and share their Charleton Heston stories.
