While Bissonnette was talking about the hot tub, he genuinely seemed a bit nervous or embarrassed for bringing it up once again, leading to himself and the other hosts saying he'll get mad again when he finds out about the clip.
It's definitely a bizarre situation, where you honestly can't tell if McDavid is in on the joke, or genuinely embarrassed and wishing Bissonnette stops. Judging by his demeanour in the most recent clip, it looks like Bissonnette was actually a bit nervous, so maybe this is actually all real.
