With a Tangled Skein could probably be dropped off as well. (Though I have a slight feeling that the Mars one was a tad cheesy with it’s Indian/Berserker bit.)
Is anyone else a food additive?
Not so far, but we do have food!
Butterscotch
Mangetout
HazelNutCoffee
Come and play!
Yo.
I also qualify as a D&D reference and an odd profession/hobby.
Wordplay includes one of my favorite posters Master Wang-Ka
Didn’t your mother ever teach you not to play with your food?
There’s a kinky joke in here somewhere. I’m just too tired to find it.

Any other building materials and/or music interludes by the band Calexico?
Airman Doors?

Anagram. Not a true one though.
My username could fall into two categories:

Zev Steinhardt
How about “Abstract Concepts”?
