Non-negotiable dimension in a relationship

[Madison85]

Q: Did you enjoy your summer research position?

A: Umm - Yes…

Q: What did you do?

A: I held down sedated Howler monkeys and measured their testicles.

They had been intrigued by great variations in both the size of the howlers’ hyoid bones in museum collections and in the size of the monkeys’ testicles as seen in the field. Dr. Knapp said that some of them are large enough that they are quite obvious “when you look up into the trees.”
