Here's a joke for you: "What do you get when you put a butterfly into a otter enclosure? An utterly delightful YouTube video."
Well, we didn't say it was a good joke, to be fair.
Uploaded by YouTuber "LifePastThisFence" back in late December, only now has the utterly endearing clip of a romp of otters trying to grab a yellow butterfly started to go viral.
Rewatching it for the fifth time, it's easy to see why - even if the YouTuber in question is keen to apologise for her shoddy camera skills.
But really, there's no need to be sorry. After all, it's a video of some otters... chasing a butterfly. What more could you want?
