This absolutely disgusting and very politically unacceptable joke is from our dear friend Joyce in England:

One day in the old peoples' home, George politely asks Joan if she will come into the corner with him and hold his willy. Joan accepts the invitation, they go off into the corner and she holds Georges willy, and everything is okay.

This goes on every day for a few days until Joan sees George in the corner with Daisy one afternoon. Joan is a little upset and later that day she asks George why he is letting Daisy touch his willy now and not her?

George replies apoligetically, "Well Joan it was very nice with you but you don't have Parkinson's disease like Daisy".
