Kate Middleton marries the wrong prince
The "beautiful cup" made by Guandong Enterprises features photos of Will and Kate with banners reading their names draped beneath.
"Crafted with the finest bone china it features an exquisite design of the happy couple with ornate gold detailing to honour this great moment in history."
Yes, when Kate stunned us all and grabbed the best man the moment she pronounced "I do."
The back of the mug reads: "The fairytale romantic union of all the centuries. 29th April 2011." You can see a video of it on the Guangdong website, where the mug is gracefully spun on a table to the sound tinned harp music.
The website, covered in hearts, cherubs and the royal crown, claims the mug was designed in China, but the Telegraph reports the company is listed in the UK, suggesting that the commemorative souvenir could be a spoof.
You have to hope "Ye Olde English Guangdong Drinkware" is a spoof.
"Please be our guests to own this esteemed, limited edition heirloom to celebrate with your work associates, friends, family and loved ones on 29th April 2011," the site extols, before warning you should purchase the $15 mug now to avoid disappointment and regret.
The mug has not been approved by St. James' Palace.
