You ask everyone to take a marker and write the letters d-j-s-a-m on their fingers in any order (one letter per finger). You then open a white board and show the definition of every letter: d is for danger, j is for joy, s is for sadness etc. (you change the letters/definitions to fit your topic). The people then have to mix and find a partner. The partner chooses one of your fingers without seeing the letter. And you must talk about the subject he chose. Then you switch.
