Three Men and a Baby (1987)
Clearly, babies were on Hollywood's mind in 1987. In this movie, three roommates (Tom Selleck, Ted Danson and Steve Guttenberg) are enjoying life in their swinging bachelor pad. Then they find a baby -- wait for it -- on their doorstep. One of the roommates is the little girl's dad, though he hadn't known about her until her surprise appearance. Alternately sweet, funny and cheesy, the movie features the obligatory adorable baby, an unnecessary subplot about drug dealers and a classic diaper-changing scene in which Selleck's character offers Guttenberg's $1,000 to take over the job. Perhaps surprisingly, this feel-good comedy is directed by Leonard Nimoy of Star Trek fame.
