When I'm cold I...

warm by the fire
warm beside the fire
warm under fire (and get a medal)
sing carols by the fire
sling carol on the fire
argue about grammar
warm marshmallows by the fire ("...and put them where?")
warm nuts by the fire
deconstruct a conflagration

The bad jokes are mine and the good ones are from the cb.

Update: corrected spelling (yet another bourgeois prejudice). :-)
