Watch Just Suppose for Free: How to Stream the Movie Online at 123Movies. . An off-camera narrator takes us through various scenarios of "just suppose". First we watch what would happen if a private detective behaved at home as he does in the movies; it's a ticket to a domestic disturbance. Next, a son gets to treat his father the way his father treats him. In the third episode, to a shopkeeper's chagrin, a man shops for a hat the way a woman does. In the final sketch, we suppose a household in which the man gets pregnant and has a baby, while the mom, clueless about little children, is the one with the career.
