Will

and

Jack

can't

wait

to

arrive

at

the

house

of

two

old

friends

who

are

known

for

their

wild

parties

but

they

discover

that

the

former

party

animals

are

now

sedately

raising

an

adopted

baby

girl

--

and

Will

shocks

Jack

when

he

volunteers

to

test

his

shaky

parenting

skills

by

babysitting

her

for

them.

Elsewhere

at

a

snooty

yacht

club,

Grace

believes

that

Karen

is

jealous

of

her

romantic

relationship

with

Ben

but

then

later

regrets

taunting

her.
