One cartoon that was nothing but inside jokes: "Gremlins from the Kremlin" Every gremlin was a caricature of a Warner Brothers animation department worker. It has a caricature of Hitler flying to Moscow in a bomber attacked by these singing gremlins. Works on both levels but its so much funnier when you can recognize the Tex Avery, Chuck Jones, etc gremlins.
How many people get the B-19 joke or the "A" card gag in Bugs Bunny these days? lol!
I remember that cartoon, although it was called Russian Rhapsody. Apparently all the gremlin were loosely based on the staff who worked at the studio.
Hey nice. I found it on youtube. Enjoy everyone.
