what you're talking about.

one more.

Robert De Niro: Come on.
Zac Efron: What if you held these
balloons right here?

birthday to Sami.
Zac Efron: What do you think
about that?
Zac Efron: What was that?
Zac Efron: Oh my gosh.
Robert De Niro: Make it record.

and don't let go this time.

with this.
Zac Efron: Ready?
Here we go.
Robert De Niro: Happy birthday to
you Sam.
Zac Efron: Dude, you didn't
even sing.
Robert De Niro: That was singing
my friend.
Zac Efron: That was not singing.
Robert De Niro: That was singing.
You didn't hear the melody.
Zac Efron: That's your problem
not mine.
Zac Efron: There's this whole song...

Robert De Niro: That's what I sang.
Zac Efron: No you didn't.

Alright, you know what?
We're done.
Zac Efron: Bob, please listen to me.
Can we just try a few more ideas?
Zac Efron: Just really quick.

Zac Efron: Happy birthday Sami!
Zac Efron: Happy birthday Sami.
Zac Efron: Blow on this.
That's awesome.
Zac Efron: Looks like a dick.
Zac Efron: Ahh!
Zac Efron: One last thing with energy,
with enthusiasm this time.
Zac Efron: Can you please light the candles
on Sami's birthday cake?
Robert De Niro: No. I'm sorry. Excuse me,
but I did the birthday message.
Robert De Niro: I sang the birthday song.
It had a lot of energy. It was perfect.
Robert De Niro: So with all due respect, the two
of you's can go fuck yourselves.
Robert De Niro: You hear that Sami.
The two of you can suck my dick.
Zac Efron: Oh my God.
You better love that.
