What parrot?!?!

The restaurant that I work at has these shirts:

I hate wearing them, because everyone always asks me about the saying.  They think there is a really good story behind it.  There really should be, but there isn't.  I can't even think of a really clever one to lie to them entertain them with.  I just end up telling them the truth, "There's no story behind it, it's just a shirt." :( The restaurant has a pirate/nautical theme to it, but that is the closest to anything about a parrot.  If anyone can think of anything to help me out, I could probably find some prize for the winning story.
