Anything worth doing is worth overdoing.

I like how you showed the difference in attitude between Rodney and Keller. Rodney might be a scientist, but the idea of switching bodies would not be appealing to him, no matter how groundbreaking the research would be. It's weirdly fitting that Keller would jump at the chance to "experiment" a little too. Meanwhile, Rodney says, "yes dear," just to be a Good Boyfriend.
