What output do you get for this:

puts 'No not since 19' + (rand(5)).to_s + (rand(10)).to_s + '!'

and what about this:

puts rand(5)
puts rand(10)

For the 30-50 part, how about getting a random number that is greater 
than or equal to 0 and less than 20 and then adding 30 to it?

In your opinion, what does the last line here do:

Your code is a mess.  You need to choose an indenting format.  Here is 
what I recommend:

x = 1

while x != 10
  if x == 1
    puts "hello"
  end

  break
end


Note:

1) The first "end" is indented the same amount as 'if', and denotes the 
end of the if statement.
2) Everything inside the while statement is indented more than 'while'
3) The last 'end' matches the indenting of 'while', and denotes the end 
of the while loop.

Without proper indenting, you will never be able to follow the logic of 
your code.
