A seventy-second animated short featuring on Google’s home page for Valentine’s Day features a gay couple among an unusual collection of romantic pairings.

As a man tries to win over a skipping woman with increasing exasperation and non-traditional gifts, it is only when he begins skipping too that she rushes over to kiss him.

A diverse montage of couples then fills the miniature screen above Google’s search term box.

A gay couple features alongside a cat and a dog, a princess and a frog, an elderly couple, a cookie embracing a carton of milk and an astronaut and an alien.

Drawing on the recent overruling of Proposition 8 in California, one amused Youtube commenter wrote: “Say NO to extraterrestrial marriage! extraterrestrial marriages are the thing that are destroying our earth! Proposition Infinity!”

The gay couple, both wearing dinner suits and standing in front of a few other people appear to be getting married.

The animation is set to Tony Bennett’s rendition of Cold Cold Heart.

Google was honoured by the Trevor Project last year for its work championing equal benefits for gay and trans employees.

In November, Google doubled its healthcare benefits for transgender employees.
