Is that a Toilet Paper he's reading in the can? Whether it's a newspaper, book, magazine or his cellphone screen, the reading isn't fast enough for the desperate little yellow mutt who's got an urgent case of the washroom willies. Your friends, family members and coworkers - especially those with pet pooches and perhaps sporadic constipation - will be letting loose a hot load of laughter and delight when you gift them the funny, comically illustrated and hilariously captioned greeting just in time for their Birthday. Literate bathroom humor at its bow wow best, in howling honor of a birth anniversary!
