Project Euler question #9 solved using Ruby

My first ever Ruby script. I'm sure this can be done neater using a list comprehension, but it works, so....

for a in (1..1000)
  for b in (1..1000)
    for c in (1..1000)
      if (a*a + b*b == c*c)
        if (a+b+c == 1000)
          print "got = " + (a*b*c).to_s + "\n"
          exit
        end
      end
    end
  end
end
