A man goes to a pet store to buy a parrot. The pet store owner shows him three parrots.
"The first one is $1000," says the owner. "He can speak three languages and sing the national anthem."
"What about the second one?" asks the man.
"The second one is $2000," says the owner. "He can speak six languages and recite Shakespeare."
"And what about the third one?" asks the man.
"The third one is $5000," says the owner.
"Wow, what can he do?" asks the man.
"Nothing," says the owner. "But the other two call him 'boss'."
