So who was hanging on for Hurley's last comment to be, "Dude!"...and not "What?"?

Yeah, i was half-expecting 'Dude', or at least 'Whoa!' Theyre probably trying to branch out Hurley's vocabulary a bit.

No,its was just that Hugo was dead serious and not in the mood for sporting his amiable 'generation x' role,with dude and the likes,when its a matter of life and death.
