Parental discretion advised

I've been getting a lot of spam recently that invites me to "enlarge [my] penis and nuts." Now, aside from the fact that I actually don't think I need any help in that department, my editor sense is highly offended by the lack of parallel construction there. I mean, come on, either use two medical terms ("penis and testicles") or two slang terms ("dinky doodle and nuts"); don't mix them in the same phrase.

Hmm, now that I think about it, isn't "Dinky Doodle and Nuts" a new cartoon on Nickelodeon?
