My /favorite/ is "ship it now, we'll fix it later" or "do it this way now and we will come back and do the better way later" and then never going back.

I've watched a few products "grow" using this method then project managers be surprised when down the line it's all held together with duct tape and chewing gum and a "simple" change is a week of work. There have been a number of times in my past where I have purposefully not suggested or the team decided not to bring up an "option" because we knew it would be abused.
