HELP!! german lightbulb ad translation?

I have a quick translation question. I found this ad in the most recent Mcsweeneys periodical that is apparently written in german. The image in the ad depicts a strange man with a lightbulb head running.
underneath the man is written the words:
leuchtet heim dem stromdieb knips! ist der beste aller tips
which translates on bablefish to: “home shines for the current thief knips is the best all tip”
you can imagine that this has not been very helpful in deciphering the meaning of the ad.
if any of you speak german and could give me a translation I would be very appreciative.
thank you,
