When I was in College I took a girl on a first date to an Italian restaurant. I ordered calamari. When it came she asked "what is that?".
I gave her a taste, and chose a particularly juicy piece of knotted tentacles. I was worried she might be squeamish so I told her
"Its a plant, you can see the roots here". Later she was indignant "I KNEW it was not a plant!".
