Obvious? Possibly. Been done before? Probably, just needed to exorcise it from my brainbox.
EXT. BUILDING SITE. DAY.
THE SITE FOREMAN IS STANDING AROUND LOOKING UP AND SCRATCHING HIS HEAD, A PEST CONTROL GUY WALKS UP TO HIM.
P\C:
Hi, I'm John from Extermapest, you must be Ian. What seems to be the problem the dispatcher wasn't clear?
FOREMAN:
Thank God you're here. It's every time we setup a site, we get the scaffolding up and bam, they move in.
WE REVEAL THAT STANDING AT THE TOP OF BUILDING SITE IS A LARGE MONKEY, HE IS CARRYING AND THREATENING TO THROW MINITURE BARRELS AT PEOPLE.
FOREMAN:
F**king monkeys!
P\C:
Don't worry we'll soon get rid of him, I'll get my best man on the job.
SUDDENLY A MAN DRESSED AS MARIO WITH A LARGE HAMMER ENTERS.
P\C:
Mario, usual drill.
