During Donald Trump's press conference tonight, many on social media weren't talking about the GOP frontrunner speaking at the podium, but the man standing behind him -- New Jersey Gov. Chris Christie.

Twitter users had fun reading all kinds of things into Christie's stone-faced expression.

A couple of Vine videos also sprouted up poking fun at the moment which have amassed hundreds of thousands of views.
