Professor T and Professor C go canoeing…

Jack doesn’t like Professor C…
Professor T: “So, Professor C and I go out to the wilderness to canoe on the river. Professor C is a city slicker, so when he catches a small fish he gets so excited that he stands up. (And you never stand up in a canoe – it’s a rule) And Professor C promptly falls out of the canoe. Do I have a duty to save Professor C?”
Jack: “Well, I’d like to say no…but…”
The Hypo Continues…
Professor T: “So after I pull Professor C out and stick him on the rocks…do I have any further duty? What if he gets hypothermic?”
(Jill starts laughing)
Professor T: “What?”
Jill: “The mental picture. It’s great.”
Professor T: “Why?”
Jill: “Because you’re going to need to provide him with your body heat!”
Professor T: “So I have to crawl into the sleeping bag with him?”
Jill: “Maybe. Or stick your dog in there with him!”
Jack: “Or you can just throw him back in water!”
