JENNA: Morning.
JERRY: Morning.
She hands him a tube of toothpaste.
JENNA: Hope you don’t mind baking soda flavour.
JERRY: (applying paste to brush) Ah, baking soda. Annoying little product. ‘I can do this. I can do that.’ Why doesn’t this stuff just shut up?
JENNA: I’m gonna grab you a towel.

Jenna leaves the bathroom. Jerry brushes his teeth. He clearly doesn’t like the taste of the baking soda, and leans over the sink to spit. He puts his hand on the counter and knocks Jenna’s toothbrush off the edge. The brush falls into the toilet bowl.

There is a shot from beneath the water in the toilet, looking up. Jerry’s face looking down into the bowl, with an expression of shock and horror.

Jerry looks behind him, to see if Jenna has spotted him. He rolls up the sleeve of his dressing gown, grimaces, and plunges his hand into the toilet. He grabs the brush out, drops it on a shelf beside the mirror and immediately begins frantically washing his hands. As he completes this task, he raises his head and finds Jenna has returned. She is standing behind him, smiling as she brushes her teeth with the brush he just retrieved from the toilet.

JERRY: Ooh-ooh
