Thanks to Brittany for this, randomly from singer Josh Groban. Josh put it on Twitter, saying:
I'm comin' at you like a [mini pony]
Literally the only thing I know about Josh Groban is that he's a singer, and far be it from me to assume how acting like a mini pony helps his singing career. I mean, he's already famous. Maybe he just knows how awesome I've become by associating myself with the tiny beasts over the years and just wants some of that great Internet action.
