Long time fan, first time poster.
Was kinda hoping someone would have brought this up by now, but since no one has....
Is there any record video or audiowise where Jack completely loses it as all his bios have claimed he did on a regular basis? I don't mean him breaking character and giggling as he seems to do on all of his live TV shows. I mean, fall on the floor, stop the show kind of fit. They showed a brief clip of him on his HBO documentary having to leave the stage because he couldn't stop laughing during a bit with Fred Allen, but that's the only thing I've seen.
Just curious, I've read so often about how he would pound the floor in uncontrollable fits, I've always wondered if any documents exist of that.
