Every time someone at work announces their pregnancy, and subsiquent months off after birth, I always want to fake a pregnancy, birth and take a couple months off until the baby "dies" and then take the couple extra weeks for grieving. I mean, it is almost entirely possible. No one has ever brought their baby in less than a couple months after it's birth, so it's not like I'd ever have to scrounge up a new born to show to everyone. I think the only catches would be:
1. no birth announcement from any hospital
2. no hosptial room for coworkers to visit, because they like to do that sort of thing
3. no newborn pics
4. I'd have to throw a fake funeral, because coworkers would probably want to be supportive and show up to something like that.
So, all I have to do is make friends in the health care and funeral industires and I'll have my ticket to the gravy train.
