Hi Zombies, try to guess where all below quotes are from?

• Coronavirus lived on surfaces until it didn’t.
• Masks didn’t work until they did, then they did not.
• There is asymptomatic transmission, except there isn’t.
• Lockdowns work to control the virus except they do not.
• All these people are sick without symptoms until, whoops, PCR tests are wildly inaccurate because they were never intended to be diagnostic tools.
• Everyone is in danger of the virus except they aren’t.
• It spreads in schools except it doesn’t.
