Ok, we saw tha CN let them show Heather blurred topless, and let Harold and Bridgette say "boobies," but what I noticed is when Geoff said LeShawna said chest, you can tell by the lip movement and on the episode quotes that they both said boobies.
To me it seems just weird how CN does things like that. Like if someone said crap, then they changed it to shoot later for another character. Does CN have a limit or something on such words?
