Unix Error Messages

At the USENIX Association conference in Atlanta recently (Ed: 1985/198
+6) 
a contest was held to invent the most humorous/bizarre/etc. UN*X error
+ 
message of the errno(2) 'EERROR' type. This contest had been tried at 
+an 
earlier European Users Group meeting, where the winning entry was

ENOTOBACCO - Read on an empty pipe

You get the idea. A partial (alphabetized) list of 'top(?)' entries fr
+om 
Atlanta (and from several readers of hp.unix) follows; if your pun/wei
+rdness 
tolerance is low, you may want to abandon ship:

EBEFOREI - Invalid syntax
ECHERNOBYL - Core dumped
ECRAY - Program exited before being run
EDINGDONG - The daemon is dead
EFLAT - System needs tuning
EGEEK - Program written by inept Frat member
EIEIO - Here-a-bug, there-a-bug, ....
EIUD - Missing period
ELECTROLUX - Your code could stand to be cleaned up
EMILYPOST - Wrong fork
END.ARMS.CONTROL - Silo overflow
ENOHORSE - Mount failed
ENONSEQUITUR - C program not derived from main(){printf("Hello, world"
+);}
EWATERGATE - Extended tape gap
EWOK - Aliens sighted
EWOK - Your code appears to have been stir-fried
EWOULDBNICE - The feature you want has not been implemented yet

And finally, a sort-of 'period piece':

EMR.ED -

    A host is a host,
    From coast to coast
    And nobody talks to a host that's close,
    Unless the host that isn't close
    Is busy, hung, or dead.

I would also like this new signal to be supported:

SIGNUKE - Nuclear event occurred (cannot be caught or ignored :-)
