Subject: Newbie loops question

I am learning Ruby as my first programming language using the excellent
tutorial by Chris Pine http://pine.fm/LearnToProgram/

Everything was going well until I tried to write a simple program to
print out the 99 bottles of beer on the wall song. Here is my code.

int = 99
while int != 1
  puts int.to_s + ' bottles of beer on the wall, ' + int.to_s + '
bottles of beer'
  int.to_i - 1
  puts 'Take one down, pass it around, '+int.to_s + ' bottles of beer on
the wall'
end

When I run this, I get into a loop of 99. It never subtracts one. I have
figured out all the other programs that you are to try, but for some
reason the problem in this is escaping me. Any help will be greatly
appreciated.

Thanks.
