Gettin' 'Em

Did you get one?
I just got one!
I just got three in a row!
Mary got five last hour.

How many do you have so far?
I got thirteen.
I only have ten.
I thought I had twenty,
but the computer says I got nineteen!

Alright, everybody get one more this hour!
Who just got one?
Did you just get one?
Did you get that one, Bart?
I want you get twice as many next hour!
You can do it -- go get 'em!
