It has been pointed out that the entire story could be much simplified.
The Ballad of Chip -n- Dale
Let me tell you all a story 'bout these chipmunk scamps
They saved a man who was cavin' in to cramps
They saw him a-squattin' and what did those rodents do?
They showed him a place where he safely could poo.
A stall that is, saved his shorts...saved his rental car.
