"The Unabomber" is one of Jake's oldest and most classic looks, and one which he never fails to pull off. I personally like this new iteration even more than the version we saw him work just last month:
I first wrote of this fashion trend (not to be confused with "The Jesus") back in 2007. At the time, I also noted that, to complete the look, he was "wearing sunglasses and sneakers and carrying a beverage cup."
Three years later (almost to the day):
