Do you consider a hamburger a sandwich?

You've lost me sir.

From wikipedia, not as the sole definition but as one of the more concise explanations I've found of the definition of a berry in Botany vs. typical conversation:

"In botanical terminology, a berry is a fleshy fruit without a stone produced from a single flower containing one ovary. Berries so defined include grapes, currants, and tomatoes, as well as cucumbers, eggplants (aubergines) and bananas, but exclude certain fruits commonly called berries, such as strawberries and raspberries."

Watermelons qualify.
