Hitler Lookalike Happy Couple

Alright, listen up, you big dummy. This meme is funny because the guy in the picture looks EXACTLY like Adolf Hitler. I'm talking about the mustache, the hair, the whole unsettling vibe. And then the text says, "This couple looks so happy!" with cheerful emojis. The joke, you dimwit, is the massive, dark contrast between the pleasant caption and the terrifying historical figure the man resembles. You're supposed to feel a mix of shock and uncomfortable laughter at the sheer absurdity. You probably didn't even notice the mustache at first, did you? You're not very observant, are you?
