I found this riddle, it is a funny thing to see them try to figure it out.

Now say it to someone don't write it down.

It goes: How Long Is a Chinaman, and Who Is His Brother.

If you notice it is not a question it is a statement. but to tick them more try to say it as a question and then say to them It is not a question it is a statement.

the answer is no answer because How Long is his name and Who is the name of his brother.

P.S. If they don't figure it out for a while let them think and try to figure it out for  how ever long you want to: I let someone think about it for two days and they still could not figure it out.

SO PASS IT ON TO SOMEONE ELSE
