I might be the last person to discover the “Harlem Shake” video, but these both causes me to snort blueberry yogurt out of my nose. Warning the visual imagery in these videos might not be suitable for all viewers.
February 20, 2013 Update: @FireCritic found 8 EMS Harlem Shake videos … he is either has too much free time or a better way to search YouTube.
Do you think it is OK to get silly at work? (and post it on YouTube?)
