He's back! Nearly two months after leaving the Late Show with a bang [1], David Letterman reemerged from retirement at Martin Short and Steve Martin's A Very Stupid Conversation show in San Antonio on Friday. Just when you thought you'd never see Dave deliver a top 10 list again, the comedian decided to call out Donald Trump on his presidential bid and controversial remarks about Mexican immigrants [2]. While Dave was on stage, the guys had to capture the moment with a selfie, which Steve later shared on Facebook.

Watch Dave's new top 10 list above, then catch up on the latest viral videos [3].
