'reply' never gets a chance to change.

Try putting your gets for reply inside the while loop at the bottom, so the
student has a chance to change their input.

Try this:

#start loop
while reply != 'yes'
  puts reply + ' ? What!?'
  if reply == 'yes'
    break
  else
    reply = gets.chomp
  end
end
