Raymond's post the other day about a giant inflatable bunny that showed up in his office finally prompted me to get off my duff and borrow a scanner from the PM in my group so I could scan in this picture:
The scan's pretty horrible, but you get the idea (I was so skinny back then :)).
The "Goat Horns" were the NT 3.1 team's idea of "Whimsical embarrassment" - basically when you broke the build, you had to wear the goat horns for the next couple of days (or until someone else broke the build).
The original goat horns got lost a year or so after we shipped NT 3.1, but we had a "wake" for Windows NT back in 2000 (when it was renamed Windows 2000), and someone went out and bought a new set of goat horns for me to wear for the party (I was the first recipient of the goat horns, and somehow I managed to become permanently associated with them). The 2nd generation horns are currently sitting in a box in my office somewhere (I think :))
