I've done doors with a 2 x 4 on older cars with very thick tops, but for most newer cars, you can just brace a knee against the door and pull it in by hand. Anyway, if it's so far off you need a lever, a piece of wood works better and doesn't mar the paint.
Glad to have that cleared-up -- I was trying to figure out how high of a jump this guy did to land on that flagpole anyway (and at what point in that effort his passenger bailed on him...).
