Not so much one line, but you have to work to keep a straight face in my Torts class because otherwise the professor will start to scream at you. This is compounded by the fact that every hypo he gives relates to death or serious injury in some form. For example, when we covered Self Defense, someone counted 15 hypos involving someone taking out a gun and shooting someone else. When that was all played out the professor started using pitbulls going for people's jugular. He also has some weird fascination with using young children in his hypotheticals. After H.E. Butt Groc. Co. v. Resendez, he gave a hypothetical of a five year old girl running down the aisle in a supermarket, slipping on a piece of cheese, and cracking her skull open. And if the hypos are not enough, in one class we spent 5 minutes discussing the proper pronunciation of "Gyro"
