Sag Mal
A game involving a sharp pencil and extrasensory perception. Named, for some reason, after German worksheets of the same name.
Player A wields the pencil and thinks of a number between 1 and 10. Player B guesses the number. If B guesses correctly, the roles are reversed. If he guesses wrongly, A stabs him in the thigh with the pencil with a shout of "Sag Mal!" for being so fatuous as to suggest a wrong number. Over time you become spookily good at it. Or you end up with very sore thighs.
