boil-in-the-bag rats
Rats used in biology dissection lessons came (dead) from a scientific supplies store in sealed plastic bags, hence the name "boil in the bag rats".
Rat's penises are remarkably similar to a grain of white rice. As this lesson was just before lunch it seemed the natural thing to do was to remove the organ and flick it into the rice salad in the canteen.

We dissected rats in Year 10 Biology. The boys paraded an opened rat, guts-a-glory, down the corridor in an attempt to nauseate the Year 9s. The girls were much more subtle. Rat foetuses make intriguing earrings.
