There's no doubt that a team of copywankers (check the definition) are working on the Liquid-Plumr account at DDB. Innuendo abound, when the lady in the hardware store reads the packaging. "Liquid-Plumr, for when you need it now".
Newsflash while she hotflashes, yes women think about sex every three minutes too. The womans' little porn-scenario that dances through her head is so perfectly portrayed by the actress, from when she bites her lip to when she giggles coyly at the hunks reply that all he needs is seven minutes. But wait there's more, us visual folks have to get in on the innuendo too and suddenly everything in the hardware store is oh-so-suggestive. From drills to giant copper pipes. Poor woman gets all dizzy as she buys Liquid-Plumr by the armful. OOh, lawdy *fans herself*, my my.
I have to hand it to everyone who worked on this, making something as unsexy as drain-de-clogger into a funny ad with a twinkle-in-the-eye erotic tinge to it is a pretty mean feat. Those copywankers should high five each other, and everyone from casting to directing too.
