One day, the three were sitting on a bench when the king's herald stopped by to deliver a message to one of them.
He asked the man sitting on the left side of the bench:
"Who's that sitting in the middle? To which the man replied: "Why that's Abe".
He then asked the man in the middle directly:
"What's your name?" and got the answer "My name's Carl."
Confused, he asked the man on the right:
"Who is that sitting in the middle?" and was immediately told: "That's Bill, of course!"
Can you help the king's herald figure out who is who?
