based on a very real thing that happened in my bio class in college
Panel one: A screen is projecting a doe-eyed gazelle looking at the viewer. In front of the screen is a bald professor saying, "Here class, we see an adorable gazelle grazing in the plains."
Panel two: There are two rows of students all in varying states of gushing over the cute gazelle. There is a collective "Awww!"
Panel three: We zoom in on the professor as he then says, "And here we see the same gazelle being attacked and eaten by a lion!" Behind the professor you can see a glimpse of the projection of some lion feet, gazelle feet, and blood.
Panel four: The same two rows of students all have varying looks of horror on their faces as they yell "AAAAHHHH!"
