For Christmas this year, my most recent daughter in law made cards for family members for the SJGames "Munchkin" game.
Those of you who appreciate the game will understand the cards. Those of you who appreciate Theremins should appreciate the idea of Theremin as Weapon...
For what it's worth, +4 is as good as it gets. (There are +5s, but they're reserved for God-mode overemphasized objects which horribly overbalance the game.)
If you play Munchkin, Jenni says you can use them.
