This guy walks into a bar, carrying a crocodile and a chicken. He sets them down on the stool next to him, and says to the (uncertain-looking) bartender "I'll have a Scotch and Soda."
Then the crocodile says "And I'll have a Whiskey Sour."
The (dumbfounded) bartender gasps "That's incredible I've never seen a crocodile that could talk!"
And the guy says "He can't the chicken is a ventriloquist."
