This amazing chart created back in 2008 by comedian and artist Doogie Horner is going viral again, and for good reason. Valentine's Day is almost here and we could all use a refresher on what works and doesn't work when it comes to pillow talk.
Memorize this entire chart (click to enlarge) and then check out some of Horner's other work here.
UPDATE: This post has been updated with a revised, more thorough version of the chart sent to us by the artist.
