So don't you think it would have been featured more if they were like the people you know? Wouldn't it make the editing really choppy if they did it constantly? Not even so much as a Thank you to the skies above for the prizes they have won thus far.
I too know similar people. Perhaps not to the extreme as you describe. But when something significant were to happen...not a millisecond would elapse before they would being praising with gratitude.
I think it came up--it was featured and we have now had a few episodes in between and then this occurred. It did seem like the guy was mega-jealous and struggled knowing that it was irrational to be THAT jealous. KWIM? Ever have one of those moments you would smack yourself for thinking something but couldn't stop thinking about it? So instead of smacking himself...he did what he did.
Anyway--that is my theory.
Your story reminds me of an episode of toddlers and tiaras...a very devout step-mom prayed about putting her step-daughter in pageants. And they were VERY devout and don't do things like Halloween...so she puts her in a Halloween pageant.

Anyway--so I can see what you mean. But I think it would have been difficult to edit that episode and omit references.
So if the snowboarders wore it on their sleeve so to speak to that extreme, I feel we would have heard far more mentions than the 2 episodes where it was a small incidental portion of the entire episode.
