In Season 7, Episode 11 (Casa Bonita) Cartman asks Kyle "When have I ever ripped on you for being a Jew?" to which there is a montage of maybe 15 of the times Cartman 'ripped on Kyle for being Jewish.'
That isn't the grand total of times that Cartman called Kyle a jew in the first seven seasons is it?
The script makes it sound like it could be by stating that Cartman 'thinks back and counts the number of times Cartman has ripped on him for being a Jew' but I am curious if anyone knows for sure.
