Alice: Did you know some people actually try to cook the rice without adding water first?
Bob: Oh come on, that's a urban legend, nobody can be that clueless and incompetent! Right, Carol?
Carol: Er… yeah, totally, I can't imagine anyone doing that… ahahaha… hem…Can overlap with an in-universe Old Shame. Compare Oblivious Guilt Slinging, Insult Friendly Fire, Innocently Insensitive and I Resemble That Remark!. Contrast Noodle Incident, where the characters vaguely talk about an event they know but the viewer doesn't. Contrast and compare Who Would Be Stupid Enough?, when Alice tempts fate and is proven right away that someone is stupid enough, and Schmuck Bait. See also It Will Never Catch On. The inverse trope is Right Behind Me, when Alice talks dirty about Bob without knowing he's, well, right behind her. Compare I'm Standing Right Here, where the person is still right there, but the mockery is less oblivious.
