I once had two parallel lines
That, when measured, diverged every time.
Ol' Euclid just shrugged
Said, "Your math's got a bug."
Nope, my negative curvature's fine.
There once was a man with a hunch.
I felt bad so I took him to lunch.
He insulted my mother, and then his own brother.
So I gave him a big FALCON PUNCH!
