Bad Day at the Office (original viral video)

Without this video, we would have never known the evolution of dance.

According to Wikipedia:

"The video clip was part of a marketing campaign by Loronix Information Systems (as of 2008 a subsidiary of Verint Systems) and stars Vinny Licciardi, the company's shipping manager. Licciardi appeared in a series of promotional videos extolling the benefits of Loronix's special brand of digital video recording systems. Loronix was the first company to develop a digital video surveillance system to replace video tape recorders. "Bad Day" was originally created and released to Loronix's manufacturer representatives. However, "Bad Day" made the largest impression and was easily distributed via e-mail thanks to its reasonable size (416KB). The origin was revealed in 1998 originally by CNN and later in print by Security Distribution Magazine. A 2005 spoof was produced by GoViral for the network security firm Netop, showing a computer fighting back."

Also, here's a pretty detailed guide to this video:

And two Wired magazine articles written about this video:

Yes I realize that this video was already uploaded to Youtube before, but this specific clip is the highest quality yet.
