Chessy but really cute penguin joke

One day a police officer was sitting along the highway doing his usual watch when a truck drove by.  The officer saw it and did a double take.  He pulled up behind the truck and sure enough he was right.  There were penguins in the back of the truck, so he pulled the truck over.  He walked up to the window to talk to the driver.  Officer: “what are you doing?  You should take those penguins to the zoo.”  Driver: “that’s a great idea.  Thanks officer.”  So the next day the officer is sitting on the same highway doing his job when the same truck drives by.  The officer can’t believe his eyes.  Did he just see what he thought?  So he pulls the truck over again.  In the back of the truck are the same penguins but they are wearing towels and sunglasses.  So the officer walks up to the window.  Officer: “I thought I told you yesterday to take those penguins to the zoo.”  Driver: “I did and we had so much fun today we are going to the beach.”
