Todd is a college student who is living at the school dorms. He has yet to pick a major, but dabbles in mad science.
For the moment, he is at the school's library, finishing a very special remote control. It is a device that can reshape the fabric of reality. To use the remote to change people, he has only to input settings, then press the "change" button.
Using the buttons and a graphical display menu, Todd can set the remote to switch sexes, modify/change clothes, increase/decrease IQ, modify knowledge, modify personality, increase/decrease lust, body size, proportions, age, species... pretty much anything about them.
The remote can be set to affect a single target, Todd himself, or have an area affect changing everyone but Todd within a set range. The remote can also freeze a single target in time, freeze everyone within a set range of Todd in time, or just freeze everything but Todd and the device.
Todd finishes the device and is ready to test it. The library doesn't have many people in it, but there are a select few targets, and if none of them are worthwhile, there's an entire town and campus to test it on, not to mention the co-ed dorms.
From where Todd sits in the corner of the library, he can spot an attractive female blonde student working at a desk, a brunette female student looking through the fiction books on a nearby shelf, an old cranky female librarian behind the library desk, and a rather out of place jock who has a lot of study material in front of him but who keeps looking at the attractive blonde.
How should Todd test the remote?
