LOL.
Some of those theories are really funny.

I especially like the 'mad about eating pineapple'.
I guess, since it was JonBenet's favorite snack that Patsy probably got mad alot and killed JonBenet several times.

Yep, locked the keys in the car.
Ain't got no spare keys and ofcourse John and Patsy have only one set of car keys between them. According to nightclub comedians, wives are always going through their husband's pockets at night, but somehow this skill eludes Patsy and she is unable to take her husband's keys.

Yet, these people could wind up as jurors.
