Twenty horrific holiday sweaters to set the mood for the Ugly Sweater Run

This Saturday, thousands of people will don their most garish Christmas sweater, head to City Park and participate in the first Denver Ugly Sweater Run. In honor of this auspicious display of festive garb and unfettered tackiness, and to possibly inspire you to join the ugly-ass fun, we searched high and low for the most horrific holiday garb we could find (and legally post, thanks to Creative Commons licensing). Settle in, grab some eggnog, and enjoy the twenty ugliest holiday sweaters the world Flickr has ever seen (so far).
