In one class I suggested that some of the dinosaur bones resembled birds and it seemed to me that they didn't go extinct but grew wings and flew away.
She told me I was an idiot, it was impossible, she growled. She further claimed that I was a vegetable so I asked her if I could be a carrot. It was likely not the best possible response but in those days I didn't know better.
BTW, those bones are now referred to as "Avian Dinosaurs" and are commonly accepted to be the forerunners of birds today.
