Damn Gloves

Isaac [putting on his coat]: “Uh oh. I lost a glove.”
Richard: “Damn it Isaac!  You can’t lose a glove everyday! Winter is just starting.”
Isaac: “Don’t say that!   ‘Damn It’ is a bad word!”
Richard: “Okay, you’re right.  I’m sorry.   But you still can’t keep losing gloves!!”
Isaac  [feeling put upon]:  “Don’t say that either!”
