science teacher: "if you curl the
fingers of your right hand around a magnet you can see what
direction the current flows in. if you don't have a right
hand, then we have a problem."
sam: "if you didn't have a right hand, wouldn't
you say that you'd be stumped?"
me: "no, no, if you don't have a right hand you just
use the one that's left."
sam: "wow, that's actually really handy!"
me: "yeah, as a rule of thumb it works pretty
well."
sam: "i'm finding this really funny but i can't
quite put my finger on why."
science teacher: "i've got to hand it to you, those
puns are currently very amusing but the two of you really need
to knuckle down and do your work."
