From a YouTube comment on this:
"This tends to happen when you crush the wire under the leg of the chair and then sit your 300lb butt down on it."
I'm sure he never sat on it, yanked it, or crimped the wire. This ONLY happens if you ABUSE the cord. Granted it isn't the most stable connection ... but it ONLY happens if you crimp the cord/yank it/etc. And no wonder the Late Show is bad with that dolt as a writer.
