The mossy camera was a K-r, and while Kai expressed it badly, the flash housing
does look odd on the K-r, like it was grafted onto a K-x to add the AF points. Kai has said in the past that he has a soft spot for Pentax and that he started out with a Pentax film body, but like so many Pentax fans, seems to express it by complaining about their shortcomings. In an average episode, he wanders around Hong Kong with a $2000 lens on a $3000 body, so I'd expect him to turn up his nose at a lowly K-r or K-01. He's referred to the Limiteds as "tasty", and got excited when he saw a tourist with a pink K-r. Most of his nonsense is for entertainment, and shouldn't be taken seriously. Now, if he behaved like a jerk with a K-5, then I'd say get out the torches and pitchforks.
I think the Strobist was joking about Alamby - he had a footnote that "some if this might be true". (tho' I have this weird dream that in person Kai is shy and geeky and Alamby cusses like a sailor...)
