What is a rabe?

I found the website for the guy who was using it on the show:

He seems to really like using the stuff, but expects everyone to know what it is I guess.

thanx!

Hey, I was just ribbing you a little.

But seriously, I have no idea what you mean about the bun being a vegetable. I’m sure it’s quite simple, but it has eluded me completely.

What’s the bun made out of?

It depends. Certainly parts of it are of vegetable origin, I doubt that all of it is. Is sodium a vegetable?

Are you suggesting that anything that has vegetable material as part of it’s component structure is a vegetable? Is a hemp shirt a vegetable?
Not trying to be a smartypants here. I just don’t see how, taxonomically, a bun is a vegetable .

Extraordinarily tasteless joke warning:

It’s sexual assault when you have a cold.

Not taxonomically, but in a round of twenty questions, a bun and a hemp shirt would be ‘vegetable’, I think.
