Do you have a smug bastard of a programmer in your office whose code always
seems to work with a minimum of debugging? If so, then heres a few #defines 
to keep them busy. 

#define main Main /* Now try to link this! */
#define stdout stderr /* No problems, until you pipe it */
#define while(x) if(x)
#define struct union /* Great space saver */

Original, and tested.
