It's Not 'Mumsie', It's 'Mumsey' ( I'm Looking At You @CrystalMazeHQ )

I don't usually intend on going all grammar nazi during my day to day activities, although I'd consider this closer to the level of spelling community support officer.

Allow me to share with you a little ditty from Series 3 Episode 9, with Richard O'Brien tinkling the Medieval ivories (anyone points out the anachronism, I'm going after your spelling, somehow)
