A woman goes into the doctor because she's missed a couple of periods andtakes a test, revealing she's pregnant. So she goes into the doctor toconfirm the results, and finds out she's about 3 1/2 months pregnant.

"Hmmmm." she says.

"Is this not good news?" He says to her.

"No, not necessarily.. The problem is that I've been with 5 different guysin the past 4 months, I have no idea who the father could be!""Well, it looks as though you may want to contact each of them and havethem come in for DNA testing. Then you'll know for sure." Said the Doc.

"I can't do that." She says.

"Why not?" The Doctor replies.

"Because, they've changed their Screen Names!!!!"
