Years ago, my brother was deployed to Kuwait. His wife was partying her way through the base. She called my mom and told her that a) she was pregnant and b) Bro's paycheck had been messed up by the pay office (this does happen in the military sometimes). Mom was horrified, of course, and sent cash as well as maternity clothes, baby care books, etc - feeling sorry for her DIL - a young, new mom-to-be whose husband was in a war zone.
Come to find out that Bro's paycheck was rolling in on schedule; she just needed more party money. There was a baby, but it was demonstrably not Bro's based on dates. The capper? After Bro had returned stateside, his (now) ex-wife and her family wanted him to claim paternity so she could have hte baby at a military hospital. Bro had to provide a DNA sample, in pre-cheek swab days, to prove it was not his baby.
