I don't think EVERY word in the thread has to be unreleated (would run out quickly), just one post compared to the previous one. So "desk lamp" doesn't have to be unrelated to "lighting", just "tardigrade".
that is what I assumed. but a desk lamp is used to produce light that is fast moving.... in the same way as your example pine tree (associatied with Christmas and thus candy canes) ain't that whut this thred'z reely all about? scootchin' up as close az yew kan git, withowt settin' off thuh larms?
I took it as the previous person trying to add a word and the next person to try and force a connection, but your way sounds like fun as wella wreath of marigolds is in the shape of a wheel
