"Hot for Teacher" may have been a major hit for Van Halen back in 1984, but the very idea of a personal relationship between teacher and student—regardless of age—was nothing to sing about for Ohio lawmakers back in the 19th century. On April 22, 1886, the Buckeye State passed a law that made it illegal for any man over the age of 21 to put the moves on a woman he was instructing. Those who dared try would face the possibility of spending up to a decade in the clink.

To be clear, while the statute quite rightly made it illegal for an adult male teacher to engage in an inappropriate relationship with one of his young students, the wide latitude of the law went far beyond that, stating:

A male person over twenty-one years of age, who is superintendent, tutor or teacher in a private, parochial or public school, or seminary or other public institution, or instructor of any female in music, dancing, roller skating, athletic exercise, or any branch of learning, who has sexual intercourse, at any time or place, with any female, with her consent, while under his instruction during the term of his engagement as superintendent, tutor or instructor, shall be imprisoned in the penitentiary not more than ten years nor less than two.

Translate that to today's standards and what it means is that, even if you're an unmarried thirty-something looking for Mr. Right, you'd be wise to keep your hands off your personal trainer, lest he be arrested for reciprocating your romantic interests. (And yes, the same goes for your roller skating instructor.)

But Ohio was hardly the first state to pass such a law. In Virginia, dangling the prospect of marriage as a way to get some nookie was a no-no with "any unmarried female of previous chaste character" and again punishable by up to 10 years in prison. (The lawmakers were generous enough to note that the "chastity of the female shall be presumed, in the absence of evidence to the contrary.") New York instituted a similar law in 1848, but considered the crime a misdemeanor (whereas Virginia classified it as a felony).

Georgia, too, had a seduction law, which reads very Jackie Collins-esque with phrases like "induce her to yield to his lustful embraces" and "allow him to have carnal knowledge of her." Any man charged with the crime had one of two choices: take his chances in court and risk spending two to 20 years in prison—or marry the gal! The written law noted that, "The prosecution may be stopped at any time by the marriage of the parties, or a bona fide and continuing offer to marry on the part of the seducer." Which was certainly one way to snag a husband!
