"Start off the day with steaming Scott's Porage Oats" sung to the tune of Scotland The Brave. And there's a pic of a brawny chap in a kilt tossing the caber (possibly to disguise an inability to spell "porridge") on said cereal box. A jolly Scots ditty and a million times less tacky than Mairi's flamin' Wedding.

In Irish it's spelled "Máire" and pronounced Moy-ra.
"Mairi" isn't even Gaelic. It's an anglicised form of a word beginning Md and/or h (far too many consonants anyway),
