Q - How do porcupines pork?
A - According to observations made at the University of Buffalo in 1946, the male walks on three legs, clutching at his genitals with the free paw. Then, he rears up, flashes his erection and covers the female with a stream of urine. This ritual continues for several weeks. When it's time to actually mate, the animals relax their spines so that the bristles lay flat.
I love ritual. This is a good one.
