Friday’s ad is for Carling’s Red Cap Ale, from 1959. It’s not the most attractive of ads, but it’s also finny, in an odd way. It starts with the setup of a joke. “Once there were two Irishmen…” and follows that up with this gem of a punchline. And “now there are millions of ’em.” They also refer to the beer below the title with this. “A most unusual ale!”
