A man went to a pet shop and asked for a bird that could sing. The proprietor brought out a gorgeous tropical bird, looked the bird in the eye, puckered his lips and started to whistle. The bird took up the very note and finished the tune with him.
“That’s mighty fine,” the customer said, “but I’d never pay money for that bird. His right leg’s crippled.”
“I thought you wanted me to sing!” cried the bird. “I gotta dance, too?”
