I don't think they should have a LOST/ALIAS crossover. I mean I think it's cool that J.J. does little things like the songs in the background, but it would be hard to pull off a cross over without it being cheesy.

It would be awesome if he did a spoof for the DVDs where Syd and the gang go to find a something on a secret island and find them...I hope JJ reads this (lol he prolly wont but, wishful thinking!!)
