"Trouble Hitting The Mark" (AKA "Someone's Having Some Trouble Hitting His Marks") is the third of six animated bloopers made for the show, supposedly taking place during the "filming" of "Rorg: A Hero of a Past."
Summary[]
In this blooper Randy continually misses the wagon in which he is supposed to land.
Trivia[]
A "mark" is an indicator, generally drawn or taped onto the floor, to an actor in a stage or screen production showing where he is supposed to stand (walk to, fall onto, etc.) in a particular scene. This is meant to ensure that the actor is near a crucial prop or other character, is not blocking the other characters from the audience, remains in proper focus, is at a place where the microphones can pick up his dialogue, etc.
Marks, of course, are not actually used in animation, since the scenes and characters are drawn into their proper places by the animator. This adds to the illusion that the series is being filmed on a physical set with live actors.
To "hit one's mark" means "to stand or go to the proper (indicated) spot for a scene." In this short, Randy ends up several time hitting his mark in a literal sense.
