As brother frankus says, "It's Christmas"! You can even use his program to generate the whole text. ;-)

On the twelfth day of YAPC my Larry gave to me
Twelve Dumpers dumping,
Eleven procs a-piping,
Ten lists a-slicing,
Nine GIFs a-dancing,
Eight REs matching,
Seven parrots singing,
Six refs a-blessing,
Five Web Techniques,
Four calling subs,
Three foreach loops,
Two DBDs,
And an Eagle book from O'Reilly!

Happy Holidays!
