A Drexel University law professor who writes kids books about Supreme Court justices is being investigated by the school after she allegedly sent her students a sexually-explicit email.

The header on Lisa McElroy’s email read "great article on writing briefs," reports rinsedaily.com.

When students clicked the link, they got anal beads instead .

More specifically, a woman engaging in a sex act using said beads.

It could all be, of course, a horrible error, or spam, or who knows what.

Hacked accounts, spam, viruses all have been known to send out inappropriate material.

Unfortunately for McElroy, even if she is cleared, the story is going viral online.

"Drexel is required to initiate fact-finding for all reports of inappropriate behaviors of a sexual nature that may impact members of our community," the Philadelphia school said in a statement, philly.com reports.

"As part of these policies and procedures, an employee may be put on administrative leave — which is not punitive — during the investigation.”

McElroy, who once appeared on the Millionaire game show, has not commented.
