“How did they figure this out? By living the dream and watching Lundgren movies all day, noting down the ones wherein he delivers a front kick, or at least a variation of it, and then comparing the average box office grosses and review scores (taken from Rotten Tomatoes) of those movies against those of the ones in which Dolph delivers no front kicks.”
Now THAT is good science, not that mamby-pamby bullshit about deciphering space/time or curing disease and hunger.
