Prompt A: red
Prompt B: toy train

red makes me think of a clown nose which makes me think of Ingrid Michaelson's "The Way I Am" which makes me think of folk music which makes me think of the Colorado forest fires which makes me think of my uncle and his guitar which makes me think of family reunions which makes me think of my grandfather which makes me think of investigating the physics of wind chimes which makes me think of my husband which makes me think of terrible puns which makes me think of popsicle sticks which make me think of summer which makes me think of playing in the basement which makes me think of our secret hideout behind the boxes in the basement which makes me think of the huge annoying piece of plywood my dad used for his model train tracks which makes me think of toy trains.

You can just list the associations, without "this makes me think of that." I wrote out my entire thought process so you could get a sense of how the game works. :)
