(The Doctor runs into the kitchen. Agatha and Donna follow)

Doctor: *Grabs Davenport* Ginger Beer!

Davenport: I beg your pardon?

Doctor: I need Ginger Beer!

Mrs. Hart: The gentleman's gone mad!

(The Doctor grabs Ginger Beer off the shelf, drinks some of it, and pours the rest over his head)

Agatha: Im an expert in poisons, Doctor! There's no cure! Its fatal!

(The Doctor spits out the Ginger Beer)

Doctor: Not for me! I can stimulate the inhibited enzymes into reversal! Protein! I need Protein!

(The Doctor breathes heavily, while Donna runs to the counter)

Donna: Walnuts!

Doctor: Brilliant!

(The Doctor upends the walnut jar and chews furiously)

(The Doctor makes muffled noises while making a shaking motion)

Donna: I cant understand you! How many words?

(The Doctor holds up one finger)

Donna: One! One word! Shake, Milkshake, Milk! Milk? No, not milk! Shake, shake, shake! Cocktail Shake! What, d'you want a Harvey Wallbanger?

Doctor: Harvey Wallbanger?

Donna: Well, I don't know!

Doctor: How is Harvey Wallbanger one word?

Agatha: What do you need, Doctor?

Doctor: Salt! I was miming salt! I need salt! I need something salty!

(Donna grabs a bag from the counter)

Donna: What about this?

Doctor: What is it?

Donna: Salt!

Doctor: That's too salty!

Donna: Oh, thats TOO SALTY!

Agatha: What about this?

(Agatha hands the Doctor a jar and he upends it, esting the food)

Donna: Whats that?

Agatha: Anchovies.

Donna: (to the Doctor) What is it? What else?

(The Doctor jolts his hands out, miming a shock)

Donna: Um, Its a song! 'Mammy'? Um, I don't know! 'Camptown races'?

Doctor: 'Camptown races'?

Donna: Well, all right, then! 'Towering Inferno'!

Doctor: It's a shock! Look, shock!
(He mimes again) I need a shock!

Donna: Right, then. Big shock. Coming up.

(Donna grabs the Doctor and plants a full frontal kiss on him. The Doctor staggers away, lifts his face up to the ceiling and releases a cloud of poisons from his body)

Doctor: (gasps) Detox! I must do that more often! (Looks at Donna apprehensively) I mean, the, the detox.

Agatha: Doctor, you are... Impossible! (The Doctor winks)
Who are you?
