OK, you folks, here's my answer to that riddle....
First of all I have to tell a short story...
In England, all public houses have names. This particular pub was called the "Pig and Whistle" (it could also just as easily have been called the "George and Dragon")
One day the landlord noticed that the sign outside his pub was looking really shabby and all the paint was peeling.

So he got in touch with a signwriter who agreed to repaint the sign.
When the signwriter had finished painting the sign, he went inside the pub and suggested to the landlord that he come outside and see if he approved of the handiwork.
The landlord came outside and looked at the sign and was not very happy.
He said to the signwriter "I say, my good man, you've left too much of a gap between the Pig and and and and and Whistle!"
