Not me personally, but my mate, lets call him J, was incredibly nervous during his wifes pregnancy around 3 years ago. He kept his car serviced, fueled up and ready to go so that as soon as her waters broke, he was ready. I think you can see where this is going huh? Yup, at 6am I get a phone call from an hysterical J, ranting that his "fething car won't start and his missus' water just broke and OMG can you take us to the hospital please?"
As soon as they got back, complete with healthy baby boy I might add, he put the car up for sale!
