A dog walker in the US was stunned to notice a remarkably endowed squirrel.
Sarah Lenzenhuber was walking her pet pooch in the US state of Missouri when she was forced to do a double take after spotting the well-hung rodent.
Lenzenhuber took a picture of the squirrel and uploaded it to Facebook where it has since received thousands of likes.
She said: "I saw him while out walking my dog, did a double take and then doubled over laughing.
"I wasn't sure if I should post it anywhere but then my childish sense of humour got the best of me."
The image led to plaudits and puns from other social media users.
One person quipped: "Wow, he's got quite the stockpile of nuts for the winter."
Another said: "Is it sad I'm jealous?"
