Origins: In fall of 2005, Shay Pierce observed two people send out the same video of Yoda rapping twice within two days to the "Not-work-related" e-mail list at his place of employment, Midway Studios Austin. Several days later, there was a separate occurrence of the same thing: one person sent out a news article which had been sent out days before. Shay responded sarcastically, saying "That's awesome... hey have you seen this video of Yoda rapping?" This began a running gag that continues to this day: anyone sending a repetitive e-mail risks being publicly yodaed. (Today the yodaing is usually done simply by pasting some image of Yoda, preferably in a "rapping" or "dancing" context.)
"Why was I yodaed?" "Because that video of the spiders on crack was posted twice already, moron."
