Got mrtg game?

One of my goals in 2008 is to realize when I’m being retarded and not cut out for this gig. So instead of banging my head against the desk for the next hour, I’m going to throw a little Vladville game that should be easy enough to answer for anyone with mrtg skills:

I want to use mrtg to plot two integer values on the same graph. I have a shell script that returns two integer values already, and I want mrtg to paint them on the same graph.

First person to post the answer in the blog comments gets a free copy of Microsoft Small Business Server 2003 R2 retail box with 5 CALs (retail ~$600).

Thanks for your help!
