On Wednesday night’s episode of The Late Show, Stephen Colbert wanted to welcome President Donald Trump back from Asia with a drink, but couldn’t quite manage the feat. Colbert’s gag was yet another person poking fun at the president for his water-drinking method, which he put on display when he, as The Late Show captioned their video, “took a break mid-speech Wednesday to wet his dog whistle.” Colbert aired a clip of the president’s press conference, which Trump paused in order to take a two-handed drink from a bottle of water.
