Here's how I suspect this thing works:

[1]: Crawl reddit.com/r/roastme

[2]: Map images to an array of "roast" comments

[3]: Compare input photo to all images from [2]

[4]: Return top three roasts from most similar image

Pretty neat, though! I've got to caution people on sharing this with coworkers as there's a very high risk of NSFW racial/ethnic/gender humor.
