A screenshot of the man's Amazon review has been posted on Reddit, where it's had more than 500,000 views.

When it comes to writing funny Amazon reviews, this man isn't foaling around.

Having ordered and received this horse's head mask, he decided to share his thoughts.

And his subsequent comment - a joking reference to the size of his own manhood - has prompted horseplay among readers.

A screenshot of the Amazon review by Ghoekstra has been posted on Reddit by shamgarbn, with the caption: "Most helpful customer review for horse head mask."

According to the grab, the item is priced at $8.50 (£5.50), and although the man's review comes with a five-star rating, it's titled: "False representation."

It says: "The good news: My horse head arrived, fits nicely and looks great. The bad news: After great debate, my wife insists I am not qualified to wear it naked."
