New thread for bitter irony! It turns out that motivators bring out the dark streak in my sense of humor. I don't want to kill teh awesome silly vibe in the other thread so I'm moving the sarcastic demotivators over here. Larger versions are available by clicking on them.
Update! I made a banner for giving proper credit to Rob and Jamie for all of the derivative works in this thread. I think that I've covered everything needed to abide by the Creative Commons License that they're using. If you use it then please make it a hyperlink to the first page of the comic like I did, otherwise I also have a larger version that you can use that displays both URLs.
