spaw
Geeeze Spaw I hate to outspaw you but as I read it, in a book written by Harlan Ellison, Science Fiction writer and pedant, but I believed him on this, was that "...one small step..." were not, as is so often misquoted, the first words spoken on the moon
Yon astronaut stood on the bottom step of the ladder and uttered almost as per script THEN stepped down onto the moon dust and said somewhat to the effect "It is some kind of dust and I can move it around with my foot". The video was tx'ed to & from California for on-line processing (even in those days) and the sound went direct so the lip sync would have been a bit off by several seconds at least.
If steps & ladders don't count then "Houston, the Eagle Has Landed" must qualify.
As a footnote - I guess being a PEDant in this context is thouroughly appropriate.
