My dad was cutting up some sweet potatoes
Him: “Do you hear that?
Me: “No”
Him: “Me either, it’s the silence of the yams”
I am not worthy.

I talk to my sweet potatoes, and they generally talk back.
Lately, they have been eerily quiet.
It must be
“Silence of the Yams.”

Why don’t sweet potatoes make any noise when you cut them up?
Because it’s the silence of the yams
