The "legendary" South American scene is completely dispensable from a plot perspective, but Harold Ramis acting stoned is eerily entrancing somehow. P.J. Soles finally has a good topless scene, for those who have been feeling that particular void for the past couple of decades.
On a demographic note: repeated viewing of the army barber scene may prove helpful in helping my three-year-old son overcome his terror of hair clippers. He has already become enamored of Bill Murrays esprit de corps, which should come in handy when were setting up the New Model Army that well be needing pretty soon now.
