I did the Expedition Everest 5K at Animal Kingdom last week and we watched the race announcers talk on stage and interview runners as we waited about an hour for our corral to get going.
Many runners dress up for these Disney races, and one time they interviewed a woman that was part of a group that were all dressed in white and covered in hundreds of different color hair bands. I forgot what they called themselves, but they explained on the big screen how it's tradition to throw your hair band at the top of the ride.
There were quite a few runners dressed up as 'disco yeti' and others as Joe Rohde, which was hilarious. Some of the Joe Rohdes looked quite good. One runner who was dressed as Rohde was interviewed on the big screen and was asked (this was a common question) what his goal for the race was. He yelled "TO FIX THE YETI!". That was funny.
