My first thought was naturally the tableware... "perfect... a Sovengard pint-mug... that'll do nicely"... but you can't pick them up, same with the decanters and candlesticks. I scoped the rest of the furnishings and found that all I could snaffle was potatoes and cabbages and the like... not really satisfactory. (Bye-the-bye whoose idea of eternal reward involves cabbages?)
Then, in a moment probably shameful to Khajiit everywhere, I tried pickpocketing the heroic departed... nothing... not even pocket-lint or a stick of gum... turns out you can't take it with you after all.
Eventually, I wound up taking the 'Roasted Ox-Head'... how I got through the battle with Alduin with that in my coat-lining I cannot imagine... it's now on the kitchen table in Honeyside..
Question is, did anyone get away with any better mementos?... preferably not requiring refrigeration.
