Behold the mathematical dad joke of the century! This meme plays on the fact that Leonhard Euler (pronounced "Oiler") has an absurd number of mathematical concepts named after him - Euler's formula, Euler's identity, Euler's method, Euler's number (e)... the list goes on forever! So when asked how he got so buff, the character says he does "ONE push-up" every time something gets named after Euler. Given Euler's 70+ formulas and theorems, that's one RIPPED mathematician! Poor guy probably never stops doing push-ups. The mathematical equivalent of drinking every time someone says "quantum" at a physics conference!
