While watching this movie, I was laughing at every scene. Tom Selleck and Steve Guttenburg are a riot as they first discover the baby sleeping at their door while their third roommate is gone to act in a movie. The first reaction is that Tom Selleck calls Guttenburg over and says, "What is this?"
"It's a baby." Guttenburg says in an innocent tone.
"I know it's a baby." You see Selleck's forced grin. "What's it doing there?"
All three men have their hands full with the baby at first, but then you see that the little baby, Mary, is beginning to grow on them. Selleck and Guttenburg both have dates while seeing a play and their other roommate, the father, is at home with Mary. When they call home at Intermission and don't get an answer, they both rush home, just to see that there was nothing wrong in the first place.
What was really hilarious was how the men had to deal with the heroin problem. In the beginning, they hear that a "package" is to be dropped off at their house, and to keep it until it's to be picked up a few days later. From the beginning, the baby is assumed to be this "package" and they try to pass her off to the heroin dealers when they arrive, just to realize their mistake right before the guys try to drive off with the baby to be put in the car trunk. But the men keep coming back to find their heroin, until the city's finest get involved to take the dealers down.
An excellent movie! I've already ordered the sequel!
