Discussion goes from how much menstrual cramps suck to how it's still preferable to having to sit on your junk every day. From there:
Me: They're just so *ugly*. (in re: penises. Because they are. Don't lie. They're not aesthetically pleasing and you know it.)
G: I know! All dangly and wrinkled...ugh. So much better having everything on the inside.
Me: It's a design flaw. I know the Bible has that whole thing about God noticing Adam was lonely and giving him a girlfriend, but really, it's God correcting the problems in the first release. We're Human 2.0.
Me: The first time Adam got kicked by the...the freaking *horse* or tripped over something. God went... "Hmmm....that's going to be a problem. We'll fix it and release a new version."
This all being accompanied by much laughter and hand gestures as we mime flipping the penis inside out and tucking it inside. Because we're five and we had the lunch room to ourselves. Ten minutes later a guy came in and couldn't understand why we were having so much fun. :D
