Pick Up Your Mail At The Post Office

two neighbor ladies were talking over the common fence
Penelope says to Gretchen "I don't know what I'm going to do, my dog bit the postman and now he won't deliver the mail".

Gretchen, ever helpful, says to Penelope, "well, get him castrated, I hear that makes them more docile".

So Penelope takes the dog to the Vet and gets the deed done, then calls the post office and asks for one more chance.

Then next day the postman delivers the mail and again gets bitten by the dog. Penelope comes running out of the house and tells the postman "I don't understand it, I had him castrated!"

The postman says to her, "lady, you should have had his teeth pulled, I wasn't worried about him screwing me!"
