On the Twelfth Day of Christmas, my network gave to me:

Twelve kiddies scripting,
Eleven users spamming,
Ten trojans listening,
Nine routers crashing,
Eight worms still probing,
Seven servers DOSing,
Six switches freezing,
Five flapping routes!
Four calling NOCs,
Three bad hubs,
Two fiber cuts,
And a virus on my brand new XP!
