Maybe it was a third nipple?
A Briton claims to have found a piece of bacon with a nipple on McDonald’s bacon roll and says it is now becoming vegan because of its “revolting” discovery.
Simon Robinson posted pictures of the “pig nipple” over the Internet and told Indy100.com, “Open it up and find out it was revolutionary. It left me completely meatless. So much so that I’m thinking about make me vegan now. “
Robinson, who claims to have OCD, opened the sandwich and gagged, saying, “I know you can find (a nipple) in the pork belly, but I didn’t order any pork belly roll. I ordered a sandwich of pork. bacon … I don’t dare eat it, but I do in the rest of the roll. ”

But Robinson has it all behind him, a McDonald’s representative said.
“We use bacon again in all our bacon rolls and, due to the location from which this cut is obtained, we are sure that this customer is wrong in his statement. We understand that the client maintains contacts with our team of attention to the customer, that offers more help ”.
