“Online” should not be confused with “on line” (like a clothesline, with clothes pegs).
     
“Can you buy clothes pegs online?” was posted on Facebook by Chris Wright on May 29, 2020. “Does anyone know if I can buy clothes pegs online?” was posted on Reddit—Oneliners on June 14, 2020 (this exact date is uncertain, however) and again on Reddit—Oneliners on November 5, 2020.
   
“Can you tell me when the next train is coming?”/“Look online” and “Have you seen the new fishing website?”/“No, it’s not online yet” and “What do you call a teller on a tightrope?”/“Online banking” are other “online” jokes.
