What would life be like without Bob and Tom cackling away during drive time? Kristi Lee would have to fend off raunchy barbs from, say, random bartenders. Chick McGee would be forced to dispense advice under the moniker of Sir Self-Evident. Steve Allee, well, he'd still have gigs playing piano, but he'd be hard-pressed to find work in the song parody world. Countless comedians wouldn't have to work off their hangovers at truck stops and diners, though they might get a little more sleep.
