While standing outside in the pouring rain, just after the fire alarm went off in the Student Wing...

Priscilla: I just want to go back to my room and stay there.
Steier: You know, Priscilla, when we go back to our building, the fire alarm will probably go off and we'll have to come out in the rain again.
Priscilla: Why would you say that??
Steier: Well, that's what'll happen according to Murphy's Law.
Priscilla: Well Murphy can suck it!
