Yes indeed it is. Time to pick which Icelandic elf you are for Christmas. For those of you who don't know the Yule lads here is a short description:

Jólasveinarnir
The Yuletide Lads

Jólasveinar first appear in the 17th century as the sons of
Grýla and Leppalúði, who had appeared in the 13th century,
and had a reputation for stealing and eating naughty children.

The Jólasveinar were counted as numbering either nine or thirteen,
but their names are at least 70.

Thirteen of the most commonly accepted names of the Jólasveinar are:

Stekkjastaur - Enclosure Post
Giljagaur - Crevice Imp
Stúfur - Itty Bitty
Þvörusleikir - Pot Scraper Licker
Pottasleikir - Pot Licker
Askasleikir - Bowl Licker
Hurðaskellir - Door Slammer

(Skyr, an Icelandic yoghurt)
Bjúgnakrækir - Sausage Snatcher
Gluggagægir - Window Peeper
Gáttaþefur - Doorway Sniffer
Ketkrókur - Meat Hooker

A few of the other names used for the Jólasveinar follow,
as they are descriptive of their natures, with an English translation:

Or they are lurking about trying to do some minor mischief.
