We need a pool on how long he will talk.
11 minutes 37 seconds.
4 minutes, 20 seconds.
It will last a little longer but it will take 40 hours to prerecord and cut and splice the pieces to make sense and make it appear live.
7 minutes, flat.
Or until his eyes glaze over and his brain freezes up, whichever comes first.................
My guess is Potatohead’s recording will be 3:42.
It would be better to separate the address in two parts:
Talking and mumbling.
Or three parts: Talking, mumbling, and babbling.
I’ll guess 5 minutes, 7 minutes, and 15 minutes.
