The words of wisdom

Today I saw a small dog shitting in the street, when it walked away, it had stuck some of the shit to a nearby wall. Thats not what pissed me off though, what pisses me off is that I can't do that, last time I tried it all just slid down the wall, and the time before that I got arrested! Ah well, there must be some sort of knack to it, or maybe i shoud start eating dog food...
