It was clear Dave and Joe had no idea who one another even were. It was an OK episode, but mostly lack luster.
Dave wanted to find an ally in Joe with all the cancel culture bullshit, and Joe mostly rebuffed him with his normal "can't read the comments" line.
Both are hardcore sport guys, but all the stuff Dave likes is completely off Joe's radar (football, baseball, etc). Dave was like "Joe, did you ever see UFC #1? That little guy would choke out everyone with his robe thingee!!" Joe was like, "um yeah... (does this fucker even know who I am?)".
They both are the whale's of their ponds and completely absorbed by their own worlds. This interaction didn't need to happen.
