and that's the problem right there: yall cats only going off the animated series, like comics havent existed long before that shyt....in fact: where do you think they got a lot of the inspiration for the series from? the comics....the only character from the series that went to the comic and not the other way around was montoya, the female cop...they dug her so much on the animated show, they gave her a book and let her become the question....
anyway, that normal family shyt does fit her character....think about it: she is smart as shyt...she knows that a normal fam type thing aint gonna happen with her/him running around being batshyt crazy and doing the shyt they do as harley/joker, so why would she want that?...she's cool doing the harley shyt cause she has him, but her ultimate goal/dream is to let that shyt go and settle down with the joker....also, the bytch was already crazy, she didnt descend into it cause of the joker like you said....yea, he helped her show it more openly and pushed her into the deep end, but she was already swimming in the crazy pool...another thing: she's not in love with the joker just cause of the crazy shyt he does, she's in love with him as a person...he could be the janitor, and she'd still love him...it just so happens he's batshyt crazy lol....
why would they change the line when it fits the character and what she was going for?...she called them pussies cause they hesitated on doing something the first time...why wouldnt she call them pussies again when they hesitated again?....what, you wouldve liked her to use another word instead of pussies to get more laughs?....
