I was actually watching youtube videos of this dude (and some of his colleagues in the Malaysia Fire Brigade) just a few days ago!
No, I did not marry a snake, says firefighter – Nation | The Star Online
I think this is him (the whole film is in Bahasa Malaysia which I hardly understand, it might be another similar dude, there appears to be more than one firefighter doing this).
These pet snakes are widely used in MY to train other firefighters how to catch less tame specimens – indeed Greater Manchester Fire sent some officers up to Kuala Lumpur to learn how to catch snakes a few years ago due to a spike in escapes of pet snakes across NW England in recent times!
I actually read several reports from blue light services and RSPCA about this phenomenon, although I am not sure why this is more of a problem in the North than the South, maybe the terraced houses and common sewers make it easier for the serpents to climb out via the neighbours WC pedestals..
