(To set the scene, we're talking about fruits)

Person A: did you know that a banana is a berry?
Teacher: really? But why? Look it up
*2 or 3 minutes later*
A: strawberries and blackberries are not fruits, but bananas, eggplants, and oranges are fruits.
(Everyone is in shock)
teacher: but why are they called berries then?
Person B: they should just call them straws then
