Why did the Joker dressed up Selina as Wonder Woman?!!
You know, after leaving her tied up (and in my opinion, beat up and even possibly raped).
I mean, at this point in time (1986), what significance would it have for Batman? It's not like he was dating WW at that point in the comics was he (I could be mistaken)?
So what was the point? Did he get confused and thought she was WW instead of Catwoman?
