...is not work safe, but is funny as hell.

This

...is work safe, but perhaps shouldn't be.

That work-safe one is described on Comedy Central's web site thus:

Electric guitar, drums or electric piano? -- Dave performs a social experiment to determine which music Blacks and Latinos most respond to.

I just want you to know that work-safe item is only the second half of the segment and totally missed the joke.

Want proof? Here's the audio of the opening of the segment. And I can't help but wonder if this is representative of the unspoken issues that have delayed season three.
