I think for me it was back in college where I thought it would be funny to laugh at someone in my class for not being able to read/speak English or French.
The class froze and the girl answers back to me saying "It is not funny"
I kindly said sorry but she hated me.

I had sex with a pig once and nothing happened. I did get a dog pregnant and had a couple of puppies that looked just like me except they could lick their own balls and stuff. Then a big snake ate them all ; the snake was called George.
