the interrupting cow [knock-knock joke]


New Member
I'm a newbie about enjoying the english joke.
I read about the "Knock Knock" joke about the interrupting cow.
But I don't quite know what does "the interrupting cow" mean.
Is there some background about it?

Thanks for helping!

    A: Knock, knock.
    B: Who's there?
    A: The interrupting cow.
    B: The interrupting cow--
    A: Moo

    In the traditional knock-knock joke, B would say "the interrupting cow who?" But he is interrupted by the mooing.

    I think that a cow was chosen for this joke because "moooo" (what an English cow says) rhymes with "who." Also, people are sometimes called cows when they are rude and obnoxious. Any animal could have been chosen but a perhaps for these two reasons a cow was chosen.

    I hadn't heard that joke and so Googled it. I will definitely use it :)

    "To interrupt" is to talk over someone else. So...

    "Knock, knock"
    "Who's there?"
    "Interrupting cow"
    "Interrupting c---"
