Those years with Jackie were prime. Imagine if Howard replaced him with Artie AND a real comedy writer? What a missed opportunity.
Anyway, if Jackie were magically allowed to return he would be as censored as anyone else. No "give Rodney a chance" jokes, or gay jokes or attacks on the big 3 or 4. The only safe targets would be the beaten to death JD, Jason, Sal and Richard. Nothing is saving the show while Howard is in PC libtard lockdown.
When I heard some of those shows from the early '90s, I initially felt a little bad for Gary over the way Jackie hammered him at times. After realizing what a douche he is from the Sirius years, I'm only sorry that Jackie didn't hit him harder.
