Explain this knock-knock joke.

You got me, Teleo. All I can see is a very unimaginative pun on 'Rob', the man's name and 'rob' meaning steal from. Still, I feel there may be another pun on the same word that I am missing.

Thanks again ,Mister Mic,

You got me.

Which do you mean, "You impressed me." or "I don't know."?

The latter.

Knock Knock
Who's there?
Robin!
Robin who?
Robin’ your house!

i can`t get it .is there anyone can tell me ?:-(

Knock-knock jokes are pretty "lame" to begin with, and these seem worse than usual. Here's one my grandchildren loved.

Knock, knock.

Who's there?

Banana. Knock, knock.

Who's there?

Banana. Knock, knock.

Who's there? (quizically)

Banana. Knock, knock.

Who's there? (impatiently)

Orange.

Orange who?

Or

TartanOrange you glad I didn't say banana?

Aren't you glad I didn't say banana again?

Instead of 'Aren't', the word 'Orange' is used here because it is probably the only fruit that rhymes with the world 'aren't'.

Wikipedia tells us that developmental psychologists study knock-knock jokes (the best known format of the pun) usage in children, as it provides valuable insight into how kids advance their language skills.

Knock knock.

Who's there?

Olive.

Olive who?

Olive you.

TartanKnock knock.

Who's there?

Olive who?

Olive you.

Is this another favourite, Tartan?
