I feel like, perhaps more so than any World Cup I can remember, the stars of the show haven't just been on the pitch; fans have taken a starring role in some of the best videos and images of the tournament.Now Colombian fans are adding themselves to my personal list of tournament all-stars along with the Tartan Army, any fan who discovered the wonders of Buc-ee's, and that one Mexican fan who dunked his head in a cotton candy machine with a wild display in Vancouver.Colombia will take on Switzerland in the final match of the Round of 16 on Tuesday afternoon in Vancouver, and boy, is the Colombian fanbase well-represented.BLUE-HAIRED WORLD CUP FAN BREAKS SILENCE AFTER HIS EMOTIONAL REACTION GOES VIRALThey turned up outside the team's hotel, and frankly, I saw shades of Beatlemania.I haven't seen the streets of Vancouver that wild since just after Game 7 of the 2011 Stanley Cup Final.Showing up outside a team's hotel has been a popular tactic this World Cup, but it was usually Mexico's fans showing up outside an opponent's hotel and making life miserable.ENGLAND STUNS MEXICO 3-2 IN INSTANT WORLD CUP CLASSIC, HANDS TEAM FIRST WORLD CUP LOSS AT ESTADIO AZTECAThey did whatever they could to make sure Ecuador had trouble getting some shut-eye, and they clobbered England's bus with foam.But this? This is a hotel visit to get your own team fired up, and that's a tactic I don't think we've seen so far.I understand how harassing an opponent in their hotel works, but let's see if Colombian fans have reverse-engineered this phenomenon to get the fellas fired up before they hit the pitch.Expect to see a lot of yellow in the stands when this one gets underway, but the Swiss have thrown neutrality to the wind, and they've got a pretty healthy representation in Vancouver as well.The match gets underway Tuesday at 4 p.m. ET on Fox, with the winner moving on to face Argentina after their shocking, come-from-behind win over Egypt.
