Favorite moments of "For me, it was Tuesday"?

Named after one of the only good moments in the Street Fighter movie, this trope means that Character A was responsible for some massive event in Character B's life, but Character A can't even remember it. So, what're your favorite examples?

In Persona 5, this a key character trait in Masayoshi Shido. His combination of insane arrogance and absurd pettiness means that he ruins lives or kills people for the crime of annoying him or being in the way, with him barely remembering it afterward. After signing Ren's fake death certificate, he vaguely remembers the name from somewhere, forgetting that he was the boy whose life he ruined. Predictably, this trait blows massive holes in his own plan, as he's made so many enemies with his thoughtless cruelty that he can't even figure out who they are.

Batman Beyond has Derek Powers. Powers is the cruel CEO of Wayne-Powers, as has done tons of horrible shit to get what he has. This includes the murder of Terry's father Warren. At the end of season 1, after his identity as Blight has been exposed and he has one last confrontation, he demands to know who Batman is. Terry says that Derek killed his father. Derek's response? A genuinely confused "Do you have the slightest idea how little that narrows it down?" Terry then follows up with "Too bad. That's all you get."
