So, Roberta, what do you like best about working here at wallmans?

Pays the bills. Well, most of them, anyway.

I also work parttime over at the sweet shoppe across the way.

They've got one of them...blending machines, you know, for the mixins...

and whenever I get bored...I do experiments.

Experiments? That's so cool.

Here, plug that in. Sorry I'm late. It's okay.

What's your best one so far?

Gee, I don't know...oh, there was one the other day and it turned out really good.

It had pralines, blueberries and a whole bunch of graham crackers.

Awesome. You know baskin-robbins?

They hire these ice cream scientists...

whose job is to invent three new flavors a month.

Really? Yeah.

You know who would be good at something like that? You.

You think so?

Oh, jeez! I gotta get back to work. Duncan's gonna have a hissy fit.

See you later.

Sorry. I know you hate it when I butt in. It's okay.

I didn't mean to mess up the whole interview.

You didn't. You were good.

So who told you? Told me what?

You found out, didn't you? We still have time for one more interview.

It's called leukemia.

Yeah, and I would like to come with you.

But are you just asking because you feel sorry for me?

I don't know. Maybe. Okay. Okay.
