Three Men and a Baby, released in 1987, starred Tom Selleck, Steve Guttenberg,
and Ted Danson. In this movie, three bachelor room
mates find a baby on the door step (the unknown product
of a fling with one of the boys). An interesting
transformation takes place, as the fellows learn
responsibility based on caring for the baby. The
sequel, Three Men and a Little Lady was released in 1990.
