"they have a definition, after all, they might be giants"
source code time baby!
you know it ain't a puzzle by me without at least ONE book cipher :)
so we're looking for a specific song by tmbg, judging by all the clues, ONE specific song: definition of good.
the numbers, when solved, indicate defition number, word, and letter.
upon doing the maths, we get:
President in a wig (07.4.1)
Sleeping in the bathtub (14.1.6)
Conversations in fake Russian accent (02.4.4)
Two flamingos engaging in a fruit fight (09.7.4)
Listening to the work of Captain Beefheart (10.1.1)
Ping pong balls are eyes (04.1.2)
Unbelievably real shadow puppets (17.3.1)
Thing that's stored in a larger version of itself (16.9.2)
...which gives us the next answer: wishlist.
