Knock Knock gets an A+ for style and office sex sensibility (and Office Space humor) for bringing out the Why I Must Have Sex With You checklist notepad and dry-erase magnet Sex Report Card — among many other wonderful things like their Pardon My French post-its, so you can literally stick a flag that says “pussy” on your cube farm neighbor’s monitor when he’s off kissing startup founder ass. Knock Knock is also the originator of the wonderful Shit List notepad, Things You Do That Really Piss Me Off checklist pad, Fashion Citations, and The Bitch Kit (for all genders). I’m also fond of their Pickups and Come-Ons book. Pickup lines about bandwidth?! I’d tap that colo-cooled ass.
