After Tweeting that pic up top with the caption, "Rock climbing with @Davidburtka today. Chill Sunday fun," NPH said, "So the rock climbing was a ruse to try and have me Punk'd. Nice try, MTV. It'll take more than a live bear destroying my car to fool NPH."

The Tweet has since been deleted (see a screengrab here), but it's nice to see Neil is as quick-witted as fans have long thought.
