Crab removes its own arm when it stops working.

[Wise Guy]

Which body part would you remove or replace?.

I need hair on my head.

 

[DannyDevito]

That won't work for me.

[Culioneros]

Holy crab.

 

[Madman]

That won't work for me.

You should bite off your little pecker!

If he was as flexible as the women he's attracted to, he just might. :biggrin2:

If this was an option for humans, there'd be millions of one armed guys walking around who had sex with some drunk 'coyote fugly' they met after last call, and then woke up first with that animal still fast asleep on top of their arm pinning them to the bed.

Given the choice between waiting for her to wake up, and chewing their own arm off in order to escape, I'm willing to bet the odds are tipped heavily in favor of gnawing the limb off at the closest joint.
