No Cody, you idiot, he's referring to an ACTUAL EXPERIMENT done with rats (Studying social hierarchies across time) where THAT actually happened. I can't remember the name of the experiment but the IS, in fact, a thing that happened and was done to rats. You can probably find the experiment on YouTube. That's where I saw it.
