This reminds me of a good Nancy Cartwright story I haven't seen elsewhere...
My old camera girl's (she was always hotter than any whore I fucked on camera) mom was an executive at Fox at The Simpsons (I think in broadcast and standards). Back years ago in the mid-90s they had a "family picnic day" at Fox for the show and had all the kids of everyone who worked there come into the sound recording studio (it sounded like the same one from the BTS on like seasons 6 or 8).
The sound guys had all the kids playing and were taking audio for them for the background noise in some episode. In the middle of recording, with all the kids who's parents worked there, Nancy came running in screaming that the children weren't union certified (SAG maybe?) and were a disgusting attempt by Fox not to pay them (her and the rest of the actors, not the kids) their proper dues and charges. She shit such a brick they stopped recording and had everyone leave.
Nancy Cartwright is a crazy psycho bitch.
