Like did you know that a sea cucumber's butthole has teeth?

That's possibly one of the strangest sentences I've ever written and you've ever read. Agreed? Well that's the beauty of social media - anything is possible.

Thanks to this tweet...

Please share a fact you are excited to know. https://t.co/vSc1kFtnKI

...Dave Moore dedicated today's Dave's World to the weird and wonderful facts offered up.

The sea cucumbers buttholes developed teeth in an attempt to keep them out.

It did not work.
