Dr. Ruth says Shark Week is ruining your sex life

Dr. Ruth Westheimer just produced the most gloriously oddball tweet we've seen in ages:

If 9 mos from now there are less births it will prove my theory re Shark Week & erections.

We're left wondering: What's her theory consist of? Does she think Shark Week is so terrifying, it prevents coitus? Or that it's so distracting, men just forget to have sex? And has anybody tracked the birth rate nine months after Shark Week in years past?
