Once, a lady wanted to but a talking parrot for herself. So she went to a pet shop owner and told him about her requirement. The shop owner said, Yes madam, I have a talking parrot. Then he showed her a parrot. The owner further said, If you pull the string on the left leg, he'll say; Hi, how are you? And if you pull the string on the right leg, he'll say; I'm fine, thank you. At this the lady asked, What if I pull both the strings? Then I would fall from this perch, you stupid lady! answered the parrot.
