Cashpoint quickie

WE SEE A SMALL QUEUE OF PEOPLE STANDING ON THE PAVEMENT LOOKING IMPATIENT.
THE WOMAN AT THE FRONT IS FINDING IT HARD TO CONTROL HERSELF.

WOMAN:
Excuse me, but are you going to be much longer.

THE CAMERA PANS TO A MAN STANDING ON ONE LEG AT A CASHPOINT MACHINE WITH HIS ARMS OUTSTRETCHED.

MAN: (TURNS HIS HEAD AROUND TO FACE THE WOMAN)
I won't be long, I'm just checking my balance.

It made me laugh.

It's good but I think I may have heard something like this before, perhaps it was as a joke rather than in visual form that you've did here.

I'm not surprised that similar jokes have been done elsewhere.
It's a fairly obvious bit of wordplay.

I thought I'd put it on critique to attempt to gauge how many times it might have been done elsewhere.
