The man raised his eyebrows during a bus trip to Manchester, England on Monday when he was seen with the animal wrapped around his neck and mouth.
A passenger who witnessed the incident told the Manchester Evening News that he initially believed the snake was a “really funky mask” until it began to glide around the railing.
“It was definitely fun,” she said.
Photos of the incident, published online, show that the unidentified man was not wearing a mask under the big brown snake.
“It doesn’t have to be a surgical mask … passengers can make their own or wear something appropriate, such as a scarf or bandana, ”the spokesman said in a statement.
“Although there is a small degree of interpretation that can be applied to this, we do not believe that it extends to the use of snake skin – especially when it is still attached to the snake.”
