While at Black Dog Salvage [1] I came across this:
[... and the Harmonic Llamas, chanting “Emmit with the hemmit and the shouldama pads.” Only two other people are expected to get this. The rest of you will just have to keep scratching your heads in puzzlement.] [2]
It obviously stands for “Black Dog Salvage” but it caught my attention because it has another meaning to me (yes, this is an inside joke from a long time ago).
