Black and White is a god video game developed by Lionhead Studios and published by Electronic Arts for Microsoft Windows in 2001 and by Feral Interactive in 2002 for Mac OS.
Following a widespread success, it was owned by Ido, who completed the game and extremely enjoyed it. The game was so successful and fun that Ido leant it to Roee, at the summer of '02, who also extremely enjoyed it.
Having completed the game, Roee returned the game to Ido, who is known for being an unorganized kid, lost it.
After some false accusations by Ido to Roee, the game was considered as lost forever. Thus the running gag came to life, of "why did Roee steal Black & White?" (although it was never stolen).
The gag is often being used when the couple exchange accusations of random deeds and facts of "false history", which is all part of the ""false history gags" of Roee and Ido":http://.
