Just how many sons does the dapper dame pictured on this hilarious Birthday card have in the joint, anyway!? Or maybe, if she can't seem to remember her one incarcerated offspring's name, she really has come up short in the motherhood department. Whatever the case, you'll be releasing a laughing long term stretch of joyous hilarity on any of your own family members, friends, workmates and fellow cons when you spring the colorfully and creatively hysterical Birthday card upon them. This failsafe funny greeting is truly the mother of all jailhouse son Birthday joke greetings.
