For the uninitiated, TBOX, or Twelve Bars of X-Mas, now in it's 23rd year, claims to be the largest bar crawl of its kind, in the world. Starting in the morning, more than 20,000 ugly sweater-wearing, naughty Santas flock to Wrigleyville, plaster themselves in branded stickers with slogans like "Why don't we just make out now and get it over with?" and drink like baby Jesus himself commanded it.
This year, the crawl takes place on Dec. 8, still in Wrigleyville, still with the same "extra" theme. Take a peek at what went down a few years ago to get yourself ready for Saturday.
