Here's my crack at it...
101.times do |n|
next if n == 0
result = ''
result += (n%3 == 0) ? 'fizz' : ''
result += (n%5 == 0) ? 'buzz' : ''
result += (result.length < 1) ? "#{n}" : ''
puts result
end

1.upto(100) do |n|
s = ""
s << "fizz" if n%3 == 0
s << "buzz" if n%5 == 0
s = "#{n}" if s.empty?
puts s
end

def fizzbuzz(n)

end
puts (1..100).map {|n| fizzbuzz(n) }

def fizzbuzz max

s.empty? ? n.to_s : s

2nd stab
1.upto(100) do |n| print (n%3 == 0) ? 'fizz' : '' puts (n%5 == 0) ? 'buzz' : (n%3 == 0) ? '' : n end

You could also use 15 as the Least common multiple of 3 and 5:
puts (1..100).map { |n| [:fizzbuzz][n%15] || [:fizz][n%3] || [:buzz][n%5] || n }

So, if we are looking for the shortest solution... I need a way to make empty string nil, but the only idea is regexp (
puts (1..50).map { |n| "#{[:fizz][n%3]}#{[:buzz][n%5]}"[/.+/] || n }

Are we playing code golf? http://perl.guru.org/scott/misc/golf.html
Wrote a Fizz Buzz http://en.wikipedia.org/wiki/Bizz_buzz#Other_uses solution in Ruby. It works but I'm sure it could be better/more concise.
