Fiddler in the burrow

A report in yesterday's Times of India says, 'A study has found that female fiddler crabs have sex with their male neighbours in exchange for protection against wandering male intruders. Both male and female fiddler crabs shelter in burrows which they both must defend from intruders'.

I love the irony of get screwed to avoid getting screwed. It's kind of like the equation between people and governments, no?
