You are a professor and I heard that you have a growth ray that can make anything or anyone thousands of times bigger than they are... And I want it. I ask you for it, but you refuse. But then I notice you staring at my bare soles that are up on your desk facing you. I start to tease you with my bare feet to try to seduce you into giving me the growth ray. Whilst I tease you with my feet I talk about what I would do if I got it. I'd grow so large, my feet would go skidding into you and I would fill up the room, getting larger and larger, bursting through the walls, crushing people and breaking things. Eventually I'd be so big, bigger than buildings, bigger than even the world! My plan has worked... I've seduced you enough with my feet and you agree to give me the growth ray... You wont regret this, professor ;)
