I recall, a number of years ago, doing a co-demo with an Arecont RSM. I was providing the VMS solution and he, providing the cameras.
Demo starts with the following...
Arecont: "Good afternoon. Let me ask you a question, do you have a camera in your phone"?
Everyone: *staring back not knowing what to say
Arecont: *sits back, crosses arms and stairs everyone down
Customer: ...Umm, yes?
Arecont: Your welcome! We invented the CCD.
Me: (in my head) Then why do you use Sony imagers?
True story, no embellishment. Craziest demo to date.
