It would be incredibly funny if he joined thinking that it'd be a group of actual fans going on about how litty and awesome he is only to find out that they were all clowning on him.
It would be funny if it didn't devolve into buddy-trolling and gayops like most of these things do. Lolcow "managers" are a plague and they spawn in these environments.
But the thought of Lit Romney joining a Discord call and getting glazed by pretend fans does make me laugh.
