Ponder that, yo

I can almost see the metaphorical lightbulb go off in her head. A moment ago, a tough question stumped the speaker into an unsteady silence. But stumped no more!

"It's behavioral stuff that's the bread, and not the peanut butter, and explodes in a viral fashion!"

Heads nod sagely throughout the meeting room. The light cast by the projector add dramatic shadow and contrast to their faces.

I'm confused. That statement conjures up images of a sandwich left out in the sun too long, perhaps at a picnic. Worse, I picture myself eating that tidbit, and experiencing the subsequent "explosion in viral fashion" in my digestive tract.

But I don't wanna look dumb. So I nod sagely too.
