which reminds me....

Mr. ENGINEER: (yelling and hitting the send button repeatedly)=
'ELLO
NOC!!!!! Testing! Testing! Testing! Testing! This is your nine=
o'clock
customer call!
(Takes RFC 791 out of the binder and thumps it on the counter.=
Throws it up
in the air and watches it plummet to the floor.)
Mr. ENGINEER: Now that's what I call a dead protocol.
NETWORK OPERATOR FROM HELL: No, no.....No, 'e's truncated!
Mr. ENGINEER: TRUNCATED!?
NOFH: Yeah! You truncated him, just as he was bein' refactored!
Datagrams truncate easily, major.
Mr. ENGINEER: Um...now look...now look, mate, I've definitely=
'ad
enough of this. That packet is definitely deceased, and when I=
deployed
it not 'alf an hour ago, you assured me that its total lack of
throughput was due to it bein' tired and shagged out following a
prolonged reroute.
NOFH: Well, he's...he's, ah...probably pining for the big iron.
Mr. ENGINEER: PININ' for the BIG IRON?!?!?!? What kind of talk=
is
that?, look, why did he fall flat on his back the moment I got=
'im
through the router?
NOFH: The 4-byte prefers keepin' on it's back! Remarkable=
protocol,
id'nit, squire? Lovely octets!
Mr. ENGINEER: Look, I took the liberty of examining that packet=
when I
dispatched it, and I discovered the only reason that it had been
sitting in its queue in the first place was that it had been=
SWAPPED
there.
(pause)
NOFH: Well, o'course it was swapped there! If I hadn't swapped=
that
packet, it would have nuzzled up to that DMZ, bent it apart with=
its
handshake, and VOOM! Feeweeweewee!
Mr. ENGINEER: "VOOM"?!? Mate, this packet wouldn't "voom" if you=
put
four million hop counts on it! 'E's bleedin' demised!
NOFH: No no! 'E's pining!
Mr. ENGINEER: 'E's not pinin'! 'E's passed on! This packet is no=
more!
He has ceased to be! 'E's expired and gone to meet 'is archive!=
'E's a
null set! Bereft of destination, 'e rests in /dev/null! If you=
hadn't
swapped 'im to the top of the queue 'e'd be pushing off the=
stack! 'Is
traceroutes are now 'istory! 'E's off the wire! 'E's kicked the=
bit
bucket, 'e's shuffled off the interwebs, run 'init 0' and joined=
the
bleedin' choir deprecated!! THIS IS AN EX-PACKET!!
