bogus fill value/return code (because it is obvious, not

 One I've often used is 0xDEADF00D, same meaning I suppose :) 
 
I've heard the 0xDEADBEEF pretty commonly to initialize empty memory.
The NeXT black hardware binaries used 0xFEEDFACE as their magic number,
and I think the fat binaries (or maybe it was the Intel?) used 0xCAFEBABE.
