Here’s a question: How many things have you heard Francis say he hates in-game? Anyone can go into the game files and look up the audio clips (I know I did… Click the ‘Random’ button at the top-right of the page), but collecting them all by actually playing through the game and hearing them all in context would be quite an… achievement? (click to embiggen)

I don’t actually know if the total number is 20, that’s a guess based on the clips that I found in the game files. The achievement image was generated by this wonderful tool, which was made by l4d-fr, a French L4D site (the site is in French, but the achievement generator is available in English).  They also have a fairly comprehensive TF2 achievement generator.

The great thing about these generators is the ability not only to generate the images, but link to them for others to see. I encourage you to do so in the comments.
