grammar

I asked Graham a question today...

He paused and replied... "uhmmmm, I thunk about it"

I interrupted. "You THUNK about it?"

him: "Mooommm, you know what I mean! I *thinked* about it!"

me: "hhhmmm, that is what I *thought* you meant....anyways....Now what were we talking about?"

him: "I have no idea with all your thinking."
