When you're in a bar, and you need to get up from your seat for a moment, have you ever felt a desire for a paper square—preferably printed with a cheeky message—that you could place on your chair as a "seat saver" until you return?

What branding initiative wouldn't be enhanced by its inclusion on a product meant to primarily sit underneath people's asses? Two more pictures of these unreasonable things [via Adrants] below.
