The telegraph clerk obviously doesn't speak dog! The dog actually said something in his language but it just sounds like barking to a person so he says to add a couple more bow wows for "free" only that would be silly/doesn't have anything to do with what he said in the telegram.
A new business was opening and one of the owner's friends wanted to send him flowers for the occasion. They arrived at the new business site and the owner read the card, "Rest in Peace."
The owner was angry and called the florist to complain.
After he had told the florist of the obvious mistake and how angry he was, the florist replied, "Sir, I'm really sorry for the mistake, but rather than getting angry, you should imagine this: somewhere there is a funeral taking place today, and they have flowers with a note saying, 'Congratulations on your new location!'"
