The “parents don’t know but they’ll talk about it anyway” gag is not a new one, but it remains a sweet one when the parents do a good job (and aren’t treated like idiots by exploitative kids). Like Karhall’s mom here, who was asked to talk about Overwatch characters without knowing who the hell they were.
