Baby Dino.

This post is about toilets, but don't get alarmed.

You know toilets that flush automatically?

Next time you use one,

listen.

Just before the water rushes into the bowl,
the flushing mechanism makes a sound like

a baby dinosaur 

waking up from a nap.

Some have asked how I know what a baby dinosaur waking up from a nap sounds like.

When you hear the toilet, you'll know.
