It is truly crazy to see something go viral (see #2 and #3 above) and travel across the country in rapid speed. Some friends in Raleigh put this video Christmas card online- Christmas Jammies-and the result has been amazing. It was picked up by Good Morning America, Huffington Post, HLN and even Mashable. The adorable Holderness family sums up their year to the tunes of Will Smith's Miami and the end result is so fun and cute, I have watched it probably 10 times myself. My little cousin in California just posted the link on Facebook sharing it with her friends after seeing it online from someone else.
