Apparently there's this British directory-information service called The Number, or possibly 118-118. And to advertise it, they've produced some goofy ads featuring these two runner guys—look, it's not going to work if I try to describe it. The key point is that on their site, you can view their parody of the famous "Cog" commercial. (Their main page may give the impression of being not work-safe, though (it says LOVE SLAVE in huge letters, among other things, and then there's an audio bit that you probably don't want playing on your speakers at work) and there doesn't appear to be a way to link directly to the ads page, so be forewarned.)
In case it's not obvious, the Cog parody is the one with the tire, currently the first ad on the list.
