It's been 15 years since Britney Spears' song "Toxic" hit airwaves but it continues to be one of the great earworms, with the people of the planet still humming the song's hooks to themselves often. You're probably humming it to yourself now just reading this. You're welcome.

Also, you're not alone. Dogs love it, too. Or, at least, one particular dog named Riley who sure as heck sounds like he's singing one of the song's memorable hooks.

Sometimes, I can't believe Twitter is free.

Editor's note: Toxicis indeed the best song ever, and clearly you need to drop what you're doing right now and listen to the whole thing. Mashable is happy to provide.

You're welcome.
