This week, Jon Stewart emerged from his post-Daily Show life of pro wrestling and beards to make fun of the RNC with his old pal Colbert on The Late Show. For the first surprise appearance, it mostly entailed spit-takes and jokes about Jeb!, but Stewart pulled out all the stops on Thursday's show.During the episode, Stewart commandeered the stage, throwing a blazer and clip-on tie over his T-shirt, and spent ten minutes laying into the Republican Convention and Trump in the way that only Stewart can."I'm not an expert on racial unity," Stewart said, "but I do believe that some of our more vaunted historical leaders in that area did retweet white supremacists less than Trump."The entire thing is worth a watch, although seeing Jon Stewart back on his game does make the gaping hole of smart political commentary during this election even more apparent. Check out the whole thing—ending with one of Stewart's most blistering rants of all time—above.Update 7/22/16: An earlier headline incorrectly stated that Stewart spoke about Trump's RNC speech.Watch Laura Benanti's Perfect Melania Trump Impression on 'The Late Show'
