Adverts on local radio can be good for laughs.
A few years back, this gem would often crop up early in the morning on Ridings FM (Wakefield area); as there seem to be no recordings of it online, I've paraphrased it from memory below. It was one of those very rare adverts that was brilliant and complete cack at the same time.

Haughty, slightly petulant young woman: I want all the latest appliances for my new kitchen, I want excellent after-sales service and I want them delivered quickly.
Put-upon husband: [sigh] You always want what you can't have, love.
Young woman: You obviously haven't been to Northern Domestics at Shaw Cross!

There was more, but at this point I usually stopped listening because anything after that golden line would only be a disappointment. Plus, quoting it out of context is a good way to get the last word in an argument.

YES.
I've found myself quoting it at people thanks to you.

It's foolproof.
Why haven't you finished the progress report!?

You obviously haven't been to Northern Domestics at Shaw Cross!

There's no comeback.
