hire some neighborhood street thugs to come over. They'll tag the whole thing for free with spraypaint

you may not even have to hire them if you live in the right (wrong?) neighborhood!

they may come over and do it without prompting, out of the kindness of thier own heart. And help clean your place up by removing some of those pesky posessions you have immorally worked so hard to aquire.

Looks like more than one sharpie to me.

very unique and clever, that's for sure! I'm afraid my artistic abilities with drawing is limited to stick people

Now that was cool! Very creative and obviously talented.

Thats creative as hell plus the time he spent drawing is incredible.

I gotta say that is very cool. I can't draw stick people let alone.... :)
