Didn't people first sperg about getting him on the show around 10 years back? If the original ebin weens didn't manage to troll him into appearing on the show, there's no way he'd go now.
And an episode with Chris would be boring as shit. He talks tough and acts like he's in command of whatever situation he's in, just as long as it's through the internet or if he's surrounded by white knights who stroke his ego. Chris on the show would just be a passive, mumbling dolt who wouldn't dare to defend his hoarding and would just lazily go along with everything. AKA very bad reality tv.
Though it'd be pretty sweet to see Barb's emaciated remains suddenly reanimate if she realizes her precious hoard is in trouble.
