Ha, ha! I had that same discussion with my brother, over a decade ago. For some reason, his wallpaper was a custom drawn penis, ejaculating. And, I think the words, "Get it all, bitch!" I used his PC for something, and saw it. One of his roomies commented that my brother .. "enhanced" the image, by suggested more definition for one of the veins.. Anyway .. I made the same suggestion: they should change it out, for something more neutral. I can image our Mother's face, if she wanted to check a movie time, or view a map of a restaurant or something - and seeing THAT, as the PC booted up!!
