He cleans up well.

The job of a campaign manager is never done!  River gives candidate Simon J. Bun a head to lean on while getting gussied up for the presidential debate.

Cleaning! Cleaning! Cleaning!

Annnd flop!

I love the progression of River using Simon as an arm-rest and his face getting smooshed.
Poor little guy thought that if he positioned himself directly under her that she'd start cleaning him too.  Unfortunately, he didn't factor in how tiring manic cleaning can be. 

Not the result he was looking for.

Simon noticed River cleaning and decided to be sneaky by attempting to nudge under her chin and get her to clean him instead...

He did get her to pause in her cleaning, which gave her time to realize...

That Simon's head was an excellent arm rest, which made her cleaning much easier!
