*makes notes*

I've encountered Egal on Duolingo by now (expanded there to 'Ist mir egal.')

Spatzen is definitely a more entertaining way of describing DOMS.

specifically, the thing you put hot pans etc on top of to protect the table/worksurface.

A trivet?

Some German idiom I met on Tumblr the other day:

"Herr, wirf Hirn vom Himmel!"
"oder Steine, Hauptsache er trifft."

(For people who aren't kaberett:
"Lord, throw some brains from the heavens."
"or stones as long as he hits the mark")

I liked the alliteration.
