Okay with all this midget talk, a little serious discussion here:
David Brent: ''Look, whether or not [he] is indeed a midget, or a dwarf--''
Warehouse guy getting fired: ''no he's a midget''
David Brent (serious): ''what's the difference?''
Guy getting fired: ''well, a dwarf is someone who has disproportionally short arms and legs--''
Brent (gesturing): ''oh right nununu, like 'at, yeah yeah''
Guy getting fired: ''it's caused by a hormone deficiency''
Brent: ''yeah, bloody hormones, yeah.''
Guy getting fired: ''a midget is still a dwarf, but their arms and legs are in proportion.''
Gareth: ''So......what's an Elf?''
...and after about 30 takes, Brent/Ricky Gervais able to get thru that with a straight face and finish out the scene.
