What was said in Eddie Murphy's "Delerious"

Here is a little question that has nagged me since the early 80’s. In Eddie Murphy’s first concert film “Delerious” (he’s wearing the red leather suit) after Eddie uses a fans camera to take a picture of his package someone in the audience yells out something and then another audience member yells back something else and the whole place erupts in laughter and Eddie Murphy loses it and laughs out of control for a few minutes and then he says “you all didn’t know I was a ventriloquist too” Does anyone know what was said by the audience members? I have listened to that tape a million times and can’t understand even a bit of it.
I honestly think if I was granted 3 wishes, one of them would be “what the hell did they say that was so funny”?. Please help
