JenderBender is a very prolific caption artist with several still active Y! groups - I know she had been on a sabbatical and recently came back with new material. Keep it up girl!
Now most of Jen's stories involve not only a gender change across generations, they usually involve an age swap (i.e. dad becomes the daughter and son becomes the mom) or even a heritage change (cacausian father/son become African-American or Asian-American sisters, etc) Me personally - just my own taste - like the basic dad>mom, son>daughter, and these two caps do that for me :)
