In case the Christmas music in your dentist’s waiting room or the influx of small children acting greedy hadn’t tipped you off, it’s the holiday season. And even though that means you’ll have to eat your way through crippling holiday-induced depression, there are some advantages to this festive month. Plenty of holiday parties, for example. You know that some asshole is inevitably going to have an ugly sweater party (probably the same guy who just forwarded you Bed Intruder), so it’s probably best to be prepared. These ten holiday sweaters are the most gruesome we could find on eBay, and at the very least, no one will see the eggnog or mulled wine you inevitably spill on yourself.[ITPGallery]
