PICKERING. They found a nest with four eggs in it:
HIGGINS. They took one apiece, and left three in it.

They laugh heartily at their own wit.

LIZA. Oh, don't be silly.

MRS. PEARCE. You mustn't speak to the gentleman like that.

LIZA. Well, why won't he speak sensible to me?

HIGGINS. Come back to business. How much do you propose to pay me
for the lessons?

LIZA. Oh, I know what's right. A lady friend of mine gets French
lessons for eighteenpence an hour from a real French gentleman.
Well, you wouldn't have the face to ask me the same for teaching
me my own language as you would for French; so I won't give more
than a shilling. Take it or leave it.

HIGGINS [walking up and down the room, rattling his keys and his
cash in his pockets] You know, Pickering, if you consider a
shilling, not as a simple shilling, but as a percentage of this
girl's income, it works out as fully equivalent to sixty or
seventy guineas from a millionaire.

PICKERING. How so?

HIGGINS. Figure it out. A millionaire has about 150 pounds a day.
She earns about half-a-crown.
