A K-9 with the Bangor, Maine, Police Department recently made headlines after he relieved himself on a Christmas tree at the Bangor International Airport.

According to a Facebook post from the department, K-9 Kari — named after the Nordic God of Wind and Winter — was confused by the tree and decided to mark his territory on the festive decoration, a “lovingly decorated representation of an authentic Maine balsam fir tree.”

The department said that Kari is a “premier explosive detection dog” and “loves keeping the Bangor International Airport free of devices that might otherwise make your flight impossible.”

Police jokingly assured the public that Kari wasn’t being a Scrooge but was rather showing his admiration for the authenticity of the tree.

“Some voiced their concerns regarding the Nordic God of Wind and Winter peeing on this tree, but their fears were allayed when Officer Mike Brennan explained that it was the tree’s realism, and not anti-Christmas sentiment, that caused Kari to let go with the yellow flow,” the department joked.

The area was then disinfected and cleansed, according to the department. A few puns and witticisms were added to conclude the post.

“While the lyrics of ‘Let It Snow’ could be easily changed to ‘Let It Flow,’ we will not ‘go there.’ Neither will Kari. I mean, not right there,” police wrote.

“A Merry Kari Christmas and a happy holiday season to all of you. Keep your hands to yourself, leave other people’s things alone, and be kind to one another. We will be (pee) here.”

A photo was included showing Kari with his tongue out  in front of his tree.
