I'm guessing Ferrell is a fan of the series since his character's name in "Jay and Silent Bob Strike Back" was Marshall Willandholly...I laughed out loud at the theater when I heard it, my wife and the other patrons apparently never watched "Land of the Lost".
One of my best friends who's 6'4" and a bit lumbering was given the nickname "Sleestack" in college, and its stuck. Perhaps he should head to Hollywood to audition.
