Jokes on you, GodzillaSpino is the reason.

Princess Celestia sipped her tea.

Suddenly, and for absolutely no reason...

Celestia opened an eye, staring straight through the fourth wall at the narrator.

Ahem. I said no reason...

Still, nothing happened. Because there was no reason to.

FOR ABSOLUTELY NO REASON--

A dinosaur burst from Celestia's teacup, sending scalding-hot leaf water in every direction. I don't know why or how, either, because there is ABSOLUTELY NO REASON, YOU HEAR ME?
