Here's an interesting article on how we humans* use sarcasm as a survival skill. While I appreciate sarcasm as light-hearted fun with friends and family, I hate it when people use sarcasm to hurt others, sarcasm that puts others down or makes fun of them.
Do you use sarcasm in your relationships? How long could you survive without using sarcasm?
*Edit: If humans use sarcasm for survival what do other animals use it for?
