למה את שואלת דבר שכזה?, וכמובן שלרמות ולשקר גם נשים יכולות
"A trope in which Eve has sex with Bob by pretending to be Alice. In short, "My God, Whom Have I Done?""
"In the classic version which gave this trope its name, Eve accomplishes her coup by slipping into bed with Bob after dark; Bob is typically too sleepy to notice the difference. This can be justified in cases where Bob and Alice have never slept together before, but if Bob and Alice are married it strains the audience's Willing Suspension of Disbelief (he can't tell the difference between Eve and his wife of five years?). Historically, it was commonly used the other way round: Eve, as the wife that Bob rejected, took the place of Alice, who was desperate to escape Bob's wooing. Nowadays it's achieved by shapeshifting or some other device by which Eve could plausibly fool Bob into believing that she is Alice."
"This is basically the definition of rape by deception (or rape by fraud), though that crime can also include lies like pretending to be a doctor and fondling someone. Not all areas recognize this crime, but in the U.S. under expanding federal definitions of rape to include any non-consensual penetration, it's very likely to be prosecuted in the same vein as all other forms of rape."
