If it's importiant to you, I think it probably was "sit Ubu sit". My recollection of things I heard last week, let alone 20 years ago, is less than perfect.

All I was really going for was some nice symetery with the package/variable names. $X::somethingelse::X. That format came from Sideshow BoB's famous die Bart die tatoo. The rest of the package names I just made up as they came to me, and I always used to hear Bubbu instead of Ubu. I'm a little crazy.

But hey, I'v been mad for years, Absolutley bonkers...
