Strike One - S3-E5
Corrected entry: In this episode, when Carrie asks Doug about ripping out the shower tile without replacing it, Doug says he was "trying to save some money around here." It doesn't make sense that he would he decide to renovate the shower tile at all while on strike and trying to save money - he would still have to purchase a lot of materials even if he did it himself. We also know from earlier in the episode that Doug is not very handy when he breaks the cupboard handle while trying to just tighten it.
Correction: Doug is a bit of a moron, probably didn't think it through before he started tearing stuff down. Then it was too late, and it HAD to be fixed.

In fairness to Doug, people often think that home repair/remodelling jobs will be easy. They are convinced that the experienced professionals want to do a simple task and charge an outrageous price. However, you can create a bigger, more expensive mess by rushing into a project and not fully understanding what you are doing.
