Bill Murray made a surprise stop by the "Late Show With David Letterman" on Wednesday, turning up at a couple of different points in the show to scratch things off his bucket list.
In one clip, Murray crashes Dave's monologue so that he can check off hosting the show, and then later he pops back up to meet Gaga and, of course, take a selfie.
Check out the Gaga/selfie clip above, and watch Murray deliver a wonderfully awkward monologue joke below.
