Even though I find Ramsay's over the top hissy fits a bit grating after a while, the bit where he gave one of the yanks an abrupt food order then followed it up with "Now did you get that? Or do you want me to email it to your fucking BlackBerry?" was ace.
The bit where he was berating the long haired squirt that he should be "poncing around doing women's hairdressing" was good as well, he said it in such a nasty way 
No offence to any yanks on the board but the US contestants are definitely of the stars'n'stripes, chest-thumping, not-very-bright "I ain't no quitter sir" variety. Zero sense of humour and self-awareness; muppets. At least with the UK contestants some of them gave as good as they got against Ramsay when they felt they were being wrongly berated; the US lot seem to be so petrified of defying authority they come across as utterly spineless and pretty pathetic.
Does make for great telly though
