Note to self: Do NOT take a selfie anywhere near a trumpeter swan.

Steven Takata was visiting the Great Bend Zoo in Kansas with his brother-in-law Jeff recently, when Jeff decided to snap a selfie with a trumpeter swan standing behind him.

The swan wasn't too happy, bobbing its head up and down before taking a bite out of Jeff's arm.

Takata captured the incident on camera and posted the video to YouTube.

The really ironic part?

"(Jeff) was trying to get the picture to send to his friend that got attacked by (a swan) years earlier to show him they weren't that bad," Takata wrote on YouTube. "It didn't turn out exactly as he planned."
