So I stayed back at my little cousin's middle school to help my old science teacher. She just happened to be teaching her kids the Human Growth and Development section of the curriculum. And I heard this conversation. Spoiler Teacher: This is why the condom is one of the contraception devices that is most effective. Kid: Excuse me, Mrs. D? Teacher: Yes, Joey? Kid: Why do they call condoms "Trojans"? Why not the Spartans? Nothing gets past the Spartans.
But the Spartans lost that battle. Calling it a Spartan would mean that it would break right before your friend could come in and finish her off.
