It's funny that you bring this topic up, because I remember as a kid being able to differentiate which shows had "smooth" blinks, and which were choppier.
South Park= 3 frames (fully open, fully shut, fully open)
Rocko= 4 frames (one with eyes fully open, one half shut, one fully shut, and again with eyes fully open)
Simpsons= 5 frames (fully open, half shut, fully shut, half shut, fully open)
