Naughty knows no age limit! Just ask good natured Granny, pictured on this hilarious Birthday card, and she'll tell you (and her shocked daughter ) a filthy sex toy tail or two. If you have an adult friend, relative or coworker who gets off on a good old fashioned dirty joke, then gift them this asininely humorous greeting on the happy and horny occasion of their latest Birthday. The black and white retro family picture and blue worded bottom delving gag wording will stick them with a good laugh and a satisfying fine feeling, to help ensure a Happy (and sensationally and salaciously exciting) Birthday.
