Four legs good. Two legs-two wheels better. 

Listen, it's important that you understand that while you're trudging through crowded city's streets, sullenly sweltering on subway platforms, and/or staring impotently across a sea of unmoving traffic on your long commute home, somewhere a lucky person is playing fetch with a pack of blissfully happy paraplegic dogs outfitted with rear-wheels:

In this particular video, that lucky person is Gritta Goetz, proprietor of the Gnadenhof Lanzenhainer Rasselbande animal sanctuary in Lanzenhain, Germany. But it's a big world, and there are probably others. It's important that you understand the vast discrepancy between how your life is and how your life could be.

Okay, maybe it's not "important," but I do think it's funny.
