And even though English isn't your primary language there are those whose language it is and couldn't understand him. Any number of things, the register of voice too low, the recording too low, using poor wording to get the idea across.
Not sure how many retakes was available in the 90's either. The 90's rejuvenated the animated cartoon. In the 80's it was done as cheaply as possible and its noticeable. More flat art as opposed to moving art.
