It wasn't until 1999 that Disney finally discovered their 1977 mouse film The Rescuers featured a tiny bit of snuck-in background nudity. Once they realized this, 3.4 million copies of the film had to be recalled at great cost.
The nudity occurs about 38 minutes into the film when the lead mice are flying through the city in a sardine can. As they quicky pass by a number of apartment windows, sharp-eyed viewers can see a topless woman pictured in one of them. Who ever planted this joke in the film had to wait over twenty years for vindication, but it must have been pretty sweet all the same.
