First read this story, about Quiet Parrot
A lady desiring companionship bought a parrot from a local pet store, complete with cage. Before purchasing it she asked for a guarantee that it would talk and was assured that it would. She took the parrot home. Then, a week and a half later, she returned to the store very disappointed.
"The parrot doesn't talk."
"Did you buy a mirror?"
"No."
"Every parrot needs a mirror."
So she bought a mirror and installed it in the parrot's cage. Another week and a half went by and she returned again.
"The parrot still doesn't talk."
"Did you buy a ladder?"
"No."
"Every parrot needs a ladder." So she bought a ladder and installed it in the cage. Another week and a half passed and she returned yet again.
"The parrot still doesn't talk."
"Did you buy a swing?"
"No."
"Every parrot needs a swing." So she bought a swing and installed it in the cage. A week and a half later she returned. She was furious! The store owner asked, "Did the parrot talk?"
"No!, he died."
"Oh, that's terrible. Did he say anything before he died?"
"Yes."
"What?"
"He gasped 'Don't they have any food down at that store?'" :)
