I've just seen the funniest TV commercial I've seen in years. It's for Midas - a chain of car repair garages.

It's narrated by a guy posing as a Midas employee. He talks about the guarantees they offer on their work.

It then cuts to him behind the Midas counter, explaining to an elderly woman customer, how all the parts they replace, come with a lifetime warranty.

She replies, "Lifetime warranty? Then can you do anything with these?"

At which point, she pulls off her coat, revealing that she's topless.

Mercifully, as she disrobes, the camera cuts to a view behind her, but we're left in no doubt that she's only wearing knickers.
