methane is odourless, yes,
They put something in household gas to make it smell for safety reasons, iirc - en.wikipedia.org/wiki/Methanethiol . That way if there's a leak you'll notice, and hopefully not spark up that lighter and WOOF.

And the man was a nutter. If you've been reading this qotw so far you'd realise a lot of them spend their time calling call centres.
