Fight

Hi.

Two gorillas, who used to be friends, was having a grudge and had decided to meet for a fight to the death. 
Monkey showed up and asked: ”Tell me, this thing you have an grudge over does it have any intrinsic value?”

”None at all.” They replied.
”And your lives, limbs and blood does that have any value for you?”
”Its priceless.” They replied.
”So you´re about to risk something priceless for something of no value?”
The gorillas decided not to fight after all.
