Word games

Is it just me, or do all translators enjoy playing with words? I used to know someone back in college who would start a conversation with: "Let's talk about ____ " It could be any word, like trees, for instance. Then I would say something like "Trees have green leaves." and this person would add: "The leaves fall off in the fall", and the game would go on like that until there was nothing left to say.

Not too long ago, I started a similar game, only it is work-related, and I use dictionaries. Take a legal word like encumbrance. The dictionary says: "Any claim or restriction on a property's title." Now I find a word in the definition I either don't know or am drawn to. Let's look up claim: "A demand for money or other relief." And then I might look up demand or relief, and so on.

Has anyone else done this? Are there any variations you would like to suggest?
