bar

A four-panel comic. A man with brown hair excitedly explains math to a woman. Panel 1: He says, "You know how h-bar is just Planck's constant h, but divided by 2·π?" She replies, "Yeah." Panel 2: Grinning, he says, "We can put a line through any constant! There's e-bar! Ø-bar! c-bar!" Panel 3: He goes on, "I don't say 'one,' I say '1-bar.' I don't call people half-wits, I call them 'π-bar-wits.'" Panel 4: The woman deadpans, "You don't call anyone anything because people don't like talking to you." He answers cheerfully, "Ah, but imagine if they did!" Votey (aftercomic): A square sheet of paper with handwritten equations applying the bar-notation joke: ħ = h/2π; 2-with-a-bar = 1/π; π-with-a-bar = 1/2; and (2-bar)·(π-bar) = 1-bar, the absurd takeaway that multiplying the barred constants equals a barred one.
