I saved the best for last. Ladies Against Humanity is the perfect combination of humor and activism; created by Kate Stayman-London when she realized:
Cards Against Humanity is awesome. Know what’s less awesome? A lack of ladies and lady-centric jokes in the comedy world, CAH included."
So she took to Tumblr and began creating her own cards. The Tumblr has been a huge success, featured in Bitch Magazine and The Huffington Post. The cards aren't currently available for download, but you can check out Rachel Rayner's similar (and equally hilarious) Feminists Against Humanity deck, which is available for download.
