Itβs a group of people who talk about everything and laugh about everythingsometimes they will talk about serious things but mostly abt fun things. They talk almost everyday.
When someone really doesn't care what you're talking about, so they decide to not listen AT ALL WHATSOEVER, THEN THEY SAY, "Who on earth cares?" and then just stomp away.
Just about the greatest comedy routine ever, by comedians Abbot and Costello, with Abott telling Costello the names of the players.
In this context, the first baseman is named "Who"; thus, the utterance "Who's on first" is ambiguous between the question ("which person is the first baseman?") and the answer ("Who is the name of the first baseman.").
"Costello: Whats the guy's name on first base?
Abott:What is the guy's name on second base Costello: Im not asking you Who's on second!
Abott: Who's on first!
Costello: I dont know!
Abott: He's on third, we are not talking about him."
"That Who's on first? Routine always makes me lol"
