I think Tribbles defend themselves by drowing you in their offspring.

I wonder if this means that tribbles are kosher. Before you start looking at me like that—I've always assumed that the reason locusts are kosher is because when you get a plague of locusts, there's damn-all else to eat after they're done with your fields. So on the same theory, would one be allowed to eat the tribbles before they reproduce you right out of house and home? And if so, does this mean that tribble parmesan is trayf?
