The 2019–20 coronavirus pandemic resulted in some requirements to wear face masks. A mask slogan became popular, but it had been suggested earlier. “How about ‘Mask it, or casket’?  Is that too catchy? Too much like ‘Click it or ticket’?  LOL Trying to get creative with it” was posted on Twitter by Daniel Skubal on April 30, 2009.

I thought up a new slogan for COVID-19.
Seat belts are… “Click it or Ticket.”
COVID-19’s new slogan…  “Mask it or Casket.”

“Mask it or Casket.”
Can we make this happen?
Remember “Click it or Ticket”?
Morons hated seatbelts but it saved lives!
Maybe we’ll start “Mask it or Casket” for the same reason?
