Side note: if they ever (God forbid) remake Spaceballs, that white Kriss Vector would be a perfect weapon for the Spaceball troopers if they can't get the Calico carbines like in the original. There's just something sci-fi about it.
(Hmmm, cosplay idea: Alex as Princess Vespa in the white dress, standing next to a Winnebago, blasting Spaceballs. "He shot my hair! Son of a bitch."
