This clip is from April 2016 from The Late Late Show with James Corden. The first half of the clip is sports-related, but not actually baseball-specific, so if you want to go straight to the baseball humor, skip to about the 2-minute mark.
This comedic bit was in response to Bryce Harper’s “Make Baseball Fun Again” cap from a couple years ago. As you would expect from late-night television, some of the jokes are a bit off-color, but he does throw in some pretty good political jabs.
