...Tigger.
Yes, Tigger.  I had a production manager at my last job who had "themed days" for tech (Pirate Day, Funny Hat Day, Hawaiian Shirt Day, Backward Cap Day, and Pajama Day), a holdover from his Community Theatre roots.
And yes, on almost every Pajama Day he would pull out his Tigger suit.  I mean the full thing from the feet to the hood with ears.
Talk about a good way to laugh at your boss.  Of course it was kinda cute.
