The 2019–20 coronavirus pandemic canceled many marathon events. “This is the first year I haven’t done the London Marathon because of Covid-19…. usually I don’t do it because I’m fat and I can’t run” is a joke that was posted on Twitter by Erik O on October 9, 2020.
 
“This is the first year I’m not going to Fiji due to Covid-19. I usually don’t go because I’m poor” and “This year I won’t be going to the Maldives because of covid19. Normally I don’t go to the Maldives because I can’t afford it“ and “This year was the first time I couldn’t travel to Europe because of Covid-19. Before this I couldn’t because I didn’t have money” are similar jokes.
