Sorry my email is acting up.  This should get what you want (I think)

array = []
char = "a"

0.upto(25) do
  array << char
  array << array[0] + char
  char = char.next
end

That is assuming you wanted to just get a..z and aa..az  if you want the
rest of the two letter combos a little tweaking should yield that.

so loud, I can't hear a word you're saying."
