Do you remember the advert with Martians, it was in fact voted the best advert ever, if I remember correctly.
"They peel them with their little knives...............then they smash them all to bits".
For Mash get Smash.
An advert for ready made/powdered mashed potato.
Look at the seller's name, a bit of a clue.
Not the real thing.
