A professional can keep their personal feelings separate from their professional responsibilities. If you feel that the former is compromising the latter, remove yourself from the situation and defer the hiring responsibilities to a colleague.

You can also ask someone else in a non-creepy way, especially by not relating the prospect of getting hired to their response to your sexual overtones (the "I don't know if I should hire you or hit on you" bit).

This isn't rocket science, its common sense and common decency, not to mention being a "professional". McClure's actions in this particularly instance are shady and creepy to the extreme.
