i've always wanted to wrote a joke, but have never been clever enough. but today i am, so here i go.
viola was showing her horse to sebastian and bragging about how smart he is. she demonstrates by asking:
"what's three plus four?"
the horse pounds its hoof against the ground seven times.
"what's two times three?"
it pounds its hoof six times.
"what's the square root of twenty-five?"
it pounds its hoof five times.
"aha!" exclaims sebastian. "your horse isn't that smart. it forgot about the negative root!"
