These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Never Live It Down: Wilbon and Reali love to remind Kornheiser that he once predicted Darko Milicic would wind up better than LeBron James. Darko, who was the 2nd pick of the 2003 draft, behind LeBron but ahead of future perennial All-Stars Carmelo Anthony, Chris Bosh, and Dwayne Wade, wound up as a bust while LeBron appears to be on track to become one of the greatest players of all time. See Reali rub it in with the video evidence here.
2003!Kornheiser: What if [Darko]'s Kevin Garnett, but BETTER?! 2012!Reali: Oh my goodness, Ton! 2012!Kornheiser: .....Oy.
Replacement Scrappy: Dan LeBatard of the Miami Herald, who often subs for Kornheiser or Wilbon when either one is unable to do the show for that day. His first appearance on the show actually deluged ESPN's mail server with anti-LeBatard mail. As a result, hating on him has become one of the show's running gags, with subsequent appearances by LeBatard introducing himself as "the Hateable Dan LeBatard". Wilbon and Kornheiser are more than happy to take their shots at him as well:
LeBatard:(opening the show)Pardon the interruption, but I'm Dan LeBatard or, as one e-mail called me, Dan LeBa-turd. Kornheiser: Oh, you got my e-mail!
Anyone other than Kornheiser or Wilbon actually. There have actually been episodes with NEITHER host.
