Every-so-often, I will pretend that I know that hell I'm doing when it comes to auto repair, just to prove that I can do something. So, I decided I would change the oil in my car. How hard could it be, right? 

Drain the old stuff into a container, replace the filter, pour the new stuff in.  Sure. Great.

Well, what sucks is when you forget to screw the drain pan plug back in before adding new oil, and you've already removed the container under your car...
[/quote]I have changed my own oil several times and can honestly say, I have never done this. I have however heard how an employee at Jiffy Lube forgot to put the drain plug back in prior to a customer driving his car off the company's property. That did not end well.
