In most versions of the Ingres dbms, "select xyzzy(")" returns "Nothing happens." However, "select xyzzy('wim')" returns "Nothing happens to Wim". The xyzzy() function has been part of the Ingres product since at least version 5 (late 1980s), but was removed from the main codeline sometime in the early 2000s. While talking to one of the members of the Ingres development team, Wim de Boer, at that time the secretary of the Ingres Users Group Nederland (IUGN), mentioned the removal of this Easter egg. This developer, who was a frequent speaker on the events organised by the IUGN, somehow managed to put the function back into the product and—especially for Wim—added handling for the 'wim' value of the parameter.
