There have been a few moments in Disney movies where someone's managed to sneak in a moment that could be interpreted in a, shall we say, non-rated G fashion. Disney's policy is to explain it away as something else and chide the public for their overactive imagination.
For instance, they claimed here that Aladdin was simply saying, "Scat, good tiger, take off and go."
And for this Little Mermaid moment, they insisted that that's the priest's knee we're looking at.
But when this moment from The Rescuers was made public, they had to (1) admit there's really no other interpretation, and (2) scrub the frames from future releases. Notice the duck in the bottom right corner of the window.
