More than 200,000 people have got involved in an internet debate about the monkey emoji.

The debate began when someone asked a question on social media: Are the monkey emojis the same monkey making three different faces, or are they three different monkeys?

Thousands of people got involved in the debate, with the final result being that 53% of the people who voted, believed it was the same monkey.

This got us thinking about some of the other popular internet debates that have happened.

How would a dog wear trousers?

It's the burning question that thousands of people across social media have been debating: How would a dog wear trousers (or 'pants', if you're American)?

It all started when a meme with an illustration of a dog wearing trousers two different ways was uploaded to social media.

What happened to Elsa and Anna from Frozen's parents?

Chris Buck, the director of Frozen and Tarzan, got Disney fans talking by saying he thinks Anna and Elsa's parents were shipwrecked on an island, where they had a baby boy, Tarzan.

He said that although the movies are not officially linked, in his mind he sees Tarzan as being Anna and Elsa from Frozen's little brother.

Is this dress blue-black or white-gold?

Back in February 2015, this dress got millions of people seriously confused as no one could decide what colour it was.

It's because colours can appear differently depending on what kind of light they're in.

Something that's blue, for example, can look totally different in sunlight, than under streetlights at night-time. Nightmare.
