Who's Your Daddy

Dan and Joe, two friends, met in the park every day to feed the pigeons, watch the squirrels and discuss world problems. One day Joe didn't show up. Dan didn't think much about it and figured maybe he had a cold or something. But after Joe hadn't shown up for a week or so, Dan really got worried. However, since the only time they ever got together was at the park, Dan didn't know where Joe lived, so he was unable to find out what had happened to him. A month had passed, and Dan figured he had seen the last of Joe, but one day, Dan approached the park and-- lo and behold! -- there sat Joe! Dan was very excited and happy to see him and told him so. Then he said, "For crying out loud Joe, what in the world happened to you?" Joe replied, "I've been in jail." "Jail!, cried Dan.  What in the world for?"
"Well", Joe said, "You know Sue, that cute little blonde waitress at the coffee shop where I sometimes go?" "Yeah, said Dan, "I remember her. What about her?" "Well, the little gold-digging witch figured I was rich and she filed rape charges against me and, at 89 years old, I was so proud that when I got into court, I pleaded guilty."
"The judge gave me 30 days for perjury."
