Pulled That Answer Out Of Her Rectum

(I am in biology. The teacher is asking questions.)

Teacher: “Do you have the right answer, [Classmate]?”

Classmate: “I do. It’s Endoplasmic Rectum.”

(Cue the laughter.)

Teacher: “Wow, ‘endoplasmic rectum?’ I usually have to worry about organism, not endoplasmic reticulum!”
