This is the kind of trolling we can get behind. Over the past month, a dancing bear has been unexpectedly popping up in the video chatrooms on Stickam, a video chat service that competes with uStream and Justin.tv.

On July 12th, the "dancing bear", Stickam user Ryan Perera, posted a compilation of his antics to YouTube (below). The result is unexpectedly hilarious, although we caution that it does contain a few curse words.

Perera writes of his escapades:

My name is Ryan Perera and I had some fun this month raiding random people's webcam chatrooms on Stickam. I wanna clear some things up as well ... 1. I'm not a Furry (I made this costume for a college video project) 2. I had 150+ different chatroom raids, I'll post some full segments next week 3. I had about 3 hours of footage to sift through :(

The bear is welcome to raid our Mashable chatroom, the Mashable Lounge, any time he likes.
