Fun fact: George Lucas based the scene on an Icelandic story about some kid who got lost outside in a snowstorm back in the day. His horse died and he had a knife... yea... fun fact...
My daughter and I were watching Star Wars The Empire Strikes Back.
She asked why Han was putting Luke in the Tauntaun.
“To keep warm,” I said.
She paused a second, then asked, “How warm is it?”; I looked at her and replied, “Lukewarm.”
