Tom Brady visited The Late Show with Stephen Colbert tonight, accepting the host’s challenge to chug a “beer.” We put the beverage in scare quotes because there’s a decent question as to what, exactly, the Super Bowl-losing quarterback actually quaffed.

Soon after the show teased Brady’s appearance, taped earlier today, eagle-eyed internetters spied that Colbert switched the arrangement of the glasses that he pulled onto his desk while looking at someone offstage. We can’t say for sure what the notoriously picky consumer slugged, but if you know, we’re listening.

(It looks like beer to me.)
