When I first heard the word "phaser," I thought it was spelled "fazer" because the weapon had a stun setting -- it could be set to just "faze" a person rather than kill them. That was in spite of the fact that "faze" is always used negatively (as in "it didn't even faze him"). So did I. It seemed a logical place to put them. That would have made the Enterprise a really tiny ship! That's because they're not hardcore Trekkies!
