Burglar Beware! Do you ever have trouble sleeping at night for fear of some miscreant entering your abode and taking food out of your refrigerator?"
"No!"
"So do I Andy, so do I. These are indeed sad times we live in. Anyhoo... I found a cheap alternative to a burglar alarm... sprinkle crisps on the floor of the kitchen."
"Monseh Munch!"
"No... they're more soggy... the thing you're trying to do is hear an audible 'crunch' should the crisps get trodden on, which will alert you to someone's presence.
"Monseh Munch are me fav'ritt!"
"Yes I know they are... but such as Tesco 'Hand Cooked' crisps are more crunchy and robust and work more effectively."
"Can I have a bag o' Monseh Munch?"
"Okay... I'll get you one from the kitchen - what flavour would you like?"
