Hail Cullum Welchers

Have you spotted CWH and the rocket silos in the new Subway advert (image grab below)?  I mean Subway the American sarnie shop, not the NY tube.

You can watch it here for now if you miss it on the telly:

(you need only watch the beginning to see CWH and ignore the rest, unless you have a thing about bacon sarnies, in which case drool away.)

CWH is obviously very zeitgeist just now!
