Tubular

The Husband and I were trying to put together some sort of supper.
"I bought asparagus at the farmer's market," I suggested.
"And we have some hot dogs and buns," he added.
I leaned over to Elder Son.  "Any other long, tubular-shaped foods you'd like for supper?"
He looked at me, then at The Husband, blinked and said, "I just ate a banana!"
