It should be possible in a single line of Python..

  pip install fizzbuzz

And then:

  import fizzbuzz
  print fizzbuzz.fizzbuzz()

Or for the second solution:

  print fizzbuzz.fizzbuzzbazz()

A tweetable (140 character) single line of Python:

print '\n'.join((lambda x:(''.join(x) if x else str(i)))([w+'zz' for (n,w) in ((3,'Fi'),(5,'Bu'),(7,'Ba')) if i%n==0]) for i in range(1,100))
