The Phoenix Five were a group of five University of California, Berkeley (Cal) students in Theta Chi who stole/liberated the Stanford Tree from the Band Shak on the campus of Stanford University in the early morning hours of October 17, 1998. The Phoenix Five held the 10-foot-tall (3.0 m) costume and university`s unofficial mascot "hostage" for two weeks, and the reaction to the heist by school administrators fueled a frenzy of media coverage which resulted in the prank being regarded as one of the most famous and notable in the history of the Big Game rivalry between Cal and Stanford. The Phoenix Five used pseudonyms to hide their true identities, going by Mr. Black, Mr. Green, Mr. Orange, Mr. White, and Mr. Yellow.
