Wojak Uses the Chain Rule

My professor: Nooo, you can't calculate ∫ e⁻ˣ², it's impossible! Me (smart): *uses the chain rule* ∫ e⁻ˣ² = −2x e⁻ˣ² + C

A crying Wojak says that calculating the integral of e⁻ˣ² is impossible, while a smug Wojak confidently applies the chain rule and writes an incorrect antiderivative. The joke is that the supposed clever solution is mathematically wrong, since the chain rule does not make this integral elementary.
