I had the... experience of working next to Brendan Eich for a while. His Throne of Skulls is no joke and I have no idea how it got past either HR or the ergonomics coach. I kept cutting myself on the damn thing when I'd bump against it, had to keep a first aid kit at my desk. We didn't even know where the skulls came from either, but more kept appearing mysteriously each day.
The laugh was annoying too. I'd be sitting there trying to work on the monolith of doom (which was actually the name for multiple technologies, but no one could decide which was doomier so we just called them all that) and all of the sudden, it's evil laughter time. Nothing breaks concentrating on code like a roar of pure malevolent guffawing. I'm sure many engineers at startups can sympathize.
Much like the rest of this comment thread, I have no idea how this much of the web happened around this man.
