LOL. You're right, Chris. I think it was the "mon" along with the "jings" that just swung it too much into 'Jings, crivens, help ma boab' territory!
'There's a moose loose aboot this hoose', and all that nonsense.
Mind you, 'tcheuchters' (look that one up if you're unfamiliar with the expression) often talk that way... But they're all 'aff their heids'!!
