Person before you will choose a word (pick nouns to make things easier). You have to make a funny or punny sentence using that word. You must leave a word for the next person to do. If person above you didn't leave a word, choose a word that's related to the one before.
ex. Cabbage
Please remove all cabbages from your baggage and pass them through the metal detector.
First word: Violin
Personally, I don't think the word violin strings along a thread like this too well. (Well is the word)
