Murder 101, Part 2

(This takes place in our biology lab.)

Instructor: “You know I used to work in a morgue? If you ever want to get away with murder I’ve got two words for ya. Potassium cyanide.”

(And then at the end of class…)

Instructor: *as we’re leaving* “See you all next week. Shoot me an email if any of you need an alibi!”
