Subject: split file into 2D array

Hello,

I have file like this (words.txt):

# 
word1 word2
word3 word4
word5 word6
word7 word8

How can I split words into 2D array in ruby ?

I just tried:

a = [[],[]]
IO.foreach("words.txt") {|line|
  unless line.strip.empty? | (line =~ (/^\#/))
  string = line.chomp.split
  a << string
 end
}

#puts a
puts [0][1]

[root@tequila2 logs]# ./logs5.rb 
nil

If I tried to print second element from array (it should be word2),I 
have got nil.

Thank you in advance
