At the Butterfly Pavilion, a class of first graders has just studied the Madagascar Hissing Cockroach and determined through observation that the female is larger than the male.

Teacher: Can anyone think of why the female is bigger?

Student: Because the female is the boy and boys are bigger.

Class dismissed!

Also, clearly the place is called the Butterfly Pavilion because if they called it the Cockroach, Scorpion, and Tarantula Pavilion That Also Has Butterflies nobody would ever volunteer to chaperone that trip.
