A crackerjack box was the disposable cardboard box used to hold popcorn or candy (sweets), though over time has come to mean a similar box or container used to give away rather useless, cheap toys and/or giveaway items. So anything referred to as 'coming out of a crackerjack box' is being derided as useless, cheap or fake.
Did you get your degree out of a Cracker jack box? (ie. your degree in media studies / sociology etc. is worthless)

(From Meatloaf's "two out of three ain't bad"): There ain't no Coupe de Ville hiding at the bottom of a Cracker jack box (you'll never find a valuable and exotic, vintage car in the bottom of a crackerjack box)

A person who is afraid to fight a man but will beat on his women and strut. A disgusting, non-bathing, rotten toothed, alcoholic who has usually burnt all his brain cells by age 12 due to huffing gasoline. A person who has had multiple run-ins with law enforcement for drugs and has yet to do any time, a lowlife who averages 1 1/2 showers per year and who has never owned a toothbrush.

3) Man, you are a cracker jack, no surprise in the box, mother fucker.
