INT.BOTTOM OF ESCALATOR.DAY
JOHN IS A SMALL MAN WITH HIS GIRLFRIEND JANET AND THEIR BIG SUITCASE AT THE BOTTOM OF SOME STAIRS
A 6FT 5 WELL BUILT GUY APPROCHES
GUY:
Can I take that?
JOHN: (NERVOUSLY)
Erm no it's okay
GUY:
I insist
JOHN:
Erm okay
GUY PICKS UP JANET AND WALKS OFF
liked this one. Have they just come down the escalator? If they're about to go up, prob best to use stairs.
Also would say "Can I take that for you?"
I EDITED the STAIRS BIT!!
yeah I was goner say that, but it's the tone of how he would say "can I take that" which will be the same as saying 'can I take that for you" as in he will emphasise the "I" (if that makes sense)
I thought it would be better for the punchline as after he picks Janet up, then it makes sense also for the reveal
(I am crap at explaining 
Thanks for feedback
I laughed!
I laughed too, didn't see that one coming, very good.
