Dumb Ways To Die was everyone's favourite ad from last year, featuring a clear and fun animation style – and a jingly song that your brain is probably singing right now. Director Julian Frost's latest project has a similarly simple style, but its for a more commercial product and a more adult audience – as it's for lubricant brand KY.

"It's fun to work with a powerful, universal idea like romantic love. You can suggest it with the simplest of character moments and hopefully it takes flight in people's minds," says Julian.

The spot is soundtracked by a cover of Cole Porter’s Let’s Do It.

"It was a privilege to add animation to such a classic, sweet, cheeky song," says Julian. "I hope Cole Porter would approve. His Wikipedia entry suggests he wasn't a bad fit for the brand.

"Cole Porter and animated humping fleas, together at last. I'm confident we'll see a blip in the US birthrate in 9 months."

The spot was directed by Julian for the New York office of Passion Pictures.
