1:

Hey,

did

you

know

that

potato

chips

wereinvented

by

mistake?

Boy

2:

Really?

What

do

you

mean?

Boy

1:

Well,

here

on

the

bag

it

says

that

they

were

invented

by

a

cook

called

George

Crum.

Boy

2:

When

was

that?

Boy

1:

Oh,

it

was

back

in

1853.

Boy

2:

So,

why

was

it

an

accident?Boy

1:

Well,

one

day,

a

customer

came

into

therestaurant

where

George

worked.

He

ordered

a

plate

of

fried

potatoes.

When

the

potatoes

came,

he

said

they

were

cut

toothick

and

sent

them

back

to

the

kitchen.

Tapescript1c1dWhile-listeningBoy

2:

So

what

happened?

Boy

1:

Well,

George

was

angry,

so

he

cut

thepotatoes

really,

really

thin,

and

he

cooked

them

for

a

long

time

until

they

were

crispy.

And

he

put

lots

of

salt

on

them

so

they

were

really

salty.

He

thought

the

customer

would

hate

them.Boy

2:

And?

Boy

1:

And

the

customer

loved

them

and

asked

for

more.

He

told

the

other

customers

about

them,

and

soon

everyone

was

ordering

thinlycut,

crispy,

salty

potato

chips.Boy

2:

And

we’re

still

eating

them

today.

What

a

cool

story!
