The Safety Word Is Shenanigans

Joe:  You would never survive a zombie apocalypse.

me:  Why would anyone want to survive a zombie apocalypse?

Joe:  There it is.  You've already been defeated.

me:  But I don't want to survive.

Joe:  Exactly.

me:  What kind of life would that be?  Fighting off zombies all the time.  What's the point?

Joe:  The best and strongest will survive.  Survival of the fittest.  That's the point of the zombie apocalypse. 

me:  Oh.  Eh, I still don't care.  When the zombies come, just put me out of my misery.

Joe:  Noted.  Will do. 

me:  Be sure, though.  Don't just see one or two zombies and off me.  Wait and confirm it's really the zombie apocalypse.

Joe:  No promises.

me:  Maybe we should have a safety word, just in case I change my mind and want to live at the last minute.

Joe:  Babe, it's the zombie apocalypse.  There isn't time!

me:  Fine.

Joe:  Told ya.  Zombie food.
