Simile
A simile is a direct comparison between two different things. The words "like" or "as" are used to create the relationship between the two entities.
"[Higgins] is in fact but for his years and size, rather like a very impetuous baby 'taking notice' eagerly and loudly, and requiring almost as much watching to keep him out of unattended mischief" (Shaw 30, Act II).
This simile compares Professor Higgins to a baby. Each has a curiosity for the natural world, and both are troublesome. Higgins concerns himself with how something will benefit him, much like a child does.
