>> It looks stupid.
>> Penny, there's no I in
justice league.
>> Look who's back.
We have Doug.
The clueless, the fun Zach.

>> Korean pop band stole my
>> You have to lean in.
>> Yeah.
>> Now I'm on the time top 100

>> Bts.
>> The army, the responsibility.
>> Do you remember your first
time on the show, on big bang?
>> I do.
I remember going in for the
audition on a Monday.
Booking it, table read was
Wednesday.
I was supposed to do one episode
and I was on the rooftop and we
were bouncing lasers off the
I thought they were going to
blow up the moon.
That was it.
But they kept bringing me back.
>> Year after year after year.
>> You became kind of this
staple for the season.
And it's returning -- will they,
won't they situation for Kaley.
>> We like Zach, how can we
bring him back, but I don't
think there was a story line
where I was ever going to be
with penny for a long time.
But I think I was a
nonthreatening ex-boyfriend they
could bring back to the show and
fans seemed to enjoy Zach every
time he appeared.
>> Theach attack.
How would you describe Zach?
>> He loves science.
Probably more than the rest of

science, he understands it or
loves it, maybe that's easier
for him.
>> What about this cast, is it

are?
>> It's incredible.

actor, it's like a family, and I
felt like family -- at first I
was like visiting the family,
and then after several seasons

like I was part of the family.
That's how friendly they are,
welcoming.
No egos, everyone is a
professional, all week long.
>> I love that.
>> This is the only family that
will pay you for the rest of
your life.
>> As soon as this show gets
picked up somewhere else.
I mean, they'll be paying you in
a residual check for the rest of
your days.
>> Residuals are real.
That's pretty cool.
>> You get to feed rose the pig.
>> What?
>> Our potential mascot.
Oh, my gosh.
>> She's not feeling today.
>> Hi, rose.
>> Hi, rose.
What's up, girl.
>> Give rose some cheerios.
>> She likes cheerios?
>> Yeah.
>> I didn't know that.
>> Hey, Rosie.
>> Hi, rose.
>> Have you ever fed a pig
>> I have not.
Now, wait,xh want to see if I
can give rose --
>> Is this a good idea?
>> Is this too much?
>> These are mascots.
>> You can feed your mascot
anything.
>> You think you'd feeds a pig
gum on television?
>> Is this big league gum going

years or something P?
>> No, she chews it and spits it
