It never ceases to amaze me how many people create stupid shit and this 'Penny Shooter Business Card' is no exception. Seriously dude, within business circumstances, how could this possibly be a good idea?
"Thank you for your attending the Annual International Astronomy Conference, I appreciate your keen attention during the question briefing regarding electromagnetism and quantum mechanics. Refreshments will be served in the lounge, please help yourself to a brochure and business card...*pew, pew pew!*..." And because the business card is the single most powerful networking tool, be generous. Take a penny, leave a penny.
