now THAT is logical

Friend's Dad:  oh, you want to marry your brother, little frank? (Frank is a dog, as his his little brother)  you know gay marriage is allowed in vermont.  would you like us to go to vermont, frankie? You know, even though gay marriage is allowed, gay incestuous marriage is still illegal, little guy.  But... you could probably make a solid argument that because you can't produce offspring together maybe they could make an incest exception for gay marriages."
