Ants in Your Bombcast

Does anyone remember the Bombcast where Jeff was talking about ants and that Chinese Chalk?

I think that was two or three weeks ago. I remember them talking about how poisonous that stuff is.

It was from 2011 i think, I heard it in the "This Year" Giantbomb best of.

There is this, that is all I can remember off the top of my head.
