you could drop the unless and the final line. ( num = 1, num-1 = 0 ;)

99.downto( 1 ) do |num|
   puts
   puts "#{num} bottles of beer on the wall, #{num} bottles of beer,"
   puts "take one down, pass it around,"
   puts "#{num-1} bottles of beer on the wall"
end

Altho I think the book hasn't covered the enumeration type stuff yet  
like downto.
