Not a chance that you are the only one to bonk her during the proper timeframe. Shes looking for the first of you fools to be foolish enough to give up the information. You think you were the only one night stand?

isn't it pretty easy to know who the father is based on the due date? i guess if she banged more than one guy that weekend she wouldnt know, but assume that you are the father for the sake of discussion. obviously a paternity test is standard in this situation.
