A policeman spots a man walking along with a penguin waddling beside him.
"Oi there, you, what you doing with that penguin?".
The man: "oh I just found him, he looked a bit lonely, so I brought him along with me"
" Don't be ridiculous," the policeman splutters, "take him to the zoo at once"
The man agrees that's a good idea and sets off towards the zoo.
A few hours later the policeman sees the pair again
"What are you doing, I told you to take that penguin to the zoo"
The man looks bewildered...'I did, and he loved it, so now I'm taking him to see a movie"
