Personally, I've gone through sleepless nights these last few months in front of a computer streaming from a Japanese site to catch up to the current season.  Luckily though, it won't take you quite that long to catch this latest quickie Youtube promo for Lost, which popped up today, and has also shown up on AintItCool. 

Season 4 rocked (review here) and we're basically in countdown (T-minus 22 days) mode until we learned where the hell the island went, why a cast member is in a coffin, and whether or not Sayid is going to do something about that hair.

Thanks to Feral for the tip.
