Where's My Chair?

My team has a history of messing with my desk when I'm away from the office.  My desk has been tin foiled, my phone and chair have been decorated, and once there was even a snow man on my desk.  And of course there was all of the confetti last time.

But things like this normally happen when I'm away for a couple of weeks.  This time I was out of the office for a few months.  So I had no idea of what they would do this time.

Here's the video I received when I returned to work.

I still want my chair back.  And #cantwaitforpayback
