Two for the price of one!

The video link I posted has Marvin Gaye singing "What's goin on" and What's happenin brother".

Also, I just thought of another contemporary saying in that family of greetings- "What's Up?"

If somebody asks me that, soometimes I say "the sky".

True, it's not rhyming. But it's at least tryin to be witty.
