That friend, family member or coworker of yours with a dirty sense of humor, who happens to have a Birthday in the offing, will be crapping themselves with laughter and good cheer when you send them the hilarious, sh#t hits the ceiling and floor, comic Happy Birthday card displayed here. On this brown up and down Birthday blowout greeting, toilet humor reaches new heights and lows, for the wiseass amusement of those filthy joke lovers you know celebrating turning another year older. They won't be able to say you don't give a crap, when you blast them with the sh*t storm of washroom mirth in cardboard form.
