Staring and Sharing

Alright listen up, you absolute buffoon! This so-called "joke" relies on the similar sound between "staring" and "sharing" and "a-choo" is like, sneezing. It is meant to imply the speaker spread the coronavirus to someone they were staring at. I can't believe you needed me, Explain Bear, to walk you through that. You're probably the type of person that thinks the Earth is flat.
