I've already told John, but I'm partial to the current hello world  
with point by point comments.  ;)

I like this one.

I wrote a fibonacci snippet a while back, but VIT Core thought it was  
a bit complex:

fib = Hash.new do |seq, i|
    if i < 2
      seq[i] = i
    else
      seq[i] = seq[i - 2] + seq[i - 1]
    end
end

0.upto(100) do |n|
    puts fib[n]
end
