luchador
Explanation
The Joke
A father catches his son pretending to be sick to skip school. But instead of punishing him, the dad conspires with the son: "Shhh. It's okay. Don't tell mom, but I got tickets to a luchador show this afternoon." The son is thrilled -- "Oh boy!" The comic then cuts to "Later..." where the "luchador" in the wrestling ring announces: "Raaa! I'm the Masked Karl Weierstrass and I'm WRESTLING with how to rigorously define the limit of a function!" The son screams "Nooooooo!"
The joke is a bait-and-switch where the father appears to be the fun, rule-breaking parent but is actually tricking his son into attending an educational event disguised as entertainment. The "luchador show" is really a math lecture delivered by someone in a wrestling costume, teaching rigorous epsilon-delta limit definitions.
The Humor
The comic works on several levels. First, there is the classic parent trap: making something educational seem fun. The son thinks he is getting rewarded for skipping school, but he is actually getting a more intense version of school. Second, the specific choice of Karl Weierstrass is perfect -- Weierstrass is famous for bringing rigor to calculus through his epsilon-delta definition of limits, which is notoriously the point in mathematics education where many students hit a wall. Having a luchador "wrestle with" the definition of a limit is both a wrestling pun and an accurate description of what students experience when they first encounter Weierstrass's formalism.
