@thedonz5 a Letterman morning show request: one time going into/out of one of those dreadful in-show news updates, (I think) Dave congratulated Edwin Newman on his newly-launched action-depicting lunchbox; am I hallucinating, or can you find/confirm?
I did a search for "lunch" in the morning show transcripts; got hits for 7 shows. Checked all, none what you're looking for. Doesn't mean you're hallucinating; only means I can't find it yet.
