Arm and Hammer - toothpaste advert (UK)

[scolear]

I remember an advert, probably from 20 years ago, where a man and a woman are in a restaurant and she rubs her foot up his leg under the table.

It's clear that she wants to have sex with him and is about to ask him if he has any condoms.

She says 'Do you have any...'

And he interrupts saying: 'Protection? Yes, I do!'

and then shows her the tube of toothpaste that he carries with him and boasts about how well it protects his teeth.

She's shocked and embarrassed by this and walks out.

Does anyone have this advert?

Thanks
