Things I learned from watching Harper

Things I learned from watching Harper:

(1) The only thing that holds the air inside car tires is the valve caps. All you need to do is remove the valve caps and the tires will deflate.

(2) Even if your Porsche has given every appearance of being driven quite fast recently, nevertheless if you haven't changed the spark plugs in 30,000 miles, it's actually so slow that any ordinary car can catch up to it in a short time even if the Porsche has had several minutes' head start.

(3) It's quite normal for a closet door to simultaneously have modern wide horizontal ventilation slats and an old-fashioned bit-key lock (i.e., the kind of lock that uses the long, spindly type of key that's sometimes incorrectly called a "skeleton key"). Also, if you lock an adult woman inside such a closet, you can expect her to be too weak or too stupid to simply kick out those relatively flimsy ventilation slats in order to escape.

(And here's one non-tongue-in-cheek thing I learned: Even if the star of your movie is a serious car enthusiast, it's at least possible that he'll be subservient enough to the script and/or to his paycheck, and/or intellectually apathetic enough, to not insist on fixing embarrassing automotive idiocies such as (1) and (2) above.)
