Ever since we started quarantining, I've only been telling inside jokes.
Inside Jokes

Listen up, dummy. The joke here is a pun, get it? "Inside jokes" has two meanings. First, it means jokes that only a certain group of people understand. Second, it means jokes told inside, 'cause the dude's been quarantining. You probably think quarantining is when you put 1/4 of something in a can, huh?
