A biology classroom. An elderly nun stands before a class of semi-attentive pre-adolescent school children, who are dressed in the traditional desert garb. She points with her ruler at charts of the male and female reproductive systems.
Nun: . . . And in the female, the ovum, which is the Latin word for egg, passes from the ovary, which is this round thing here, into the fallopian tube . . . this thing here, which is almost as ugly as this naughty thing on the male chart . . .
A boy raises his hand.
Nun: Yes, Adam?
Boy: What’s the naughty thing called, in Latin?
Nun:(Quickly) God only knows, next question?
