The amount of abuse I hurled at Carsten Haitzler (Raster) during our time at VA Linux (where he worked on E as well as other stuff) was a complete sitcom unto itself; at one point he debated making a "zeruch insult generator" just to streamline the verbal abuse process.

I loved using the environment but would regularly harangue him for being glib on resource usage. It really was otherwise very ahead of the curve.
