When and how did "like" come to mean "said"?

For an example of what I am talking about here, consider this sentence:

"So, I saw her the other day, and I was like, 'Hey, how are you?' and then she was like, "I'm good, how are you?'"

When and how did "like" become regularly used in this context in English? Is it related to the use of "like" as a filler word?
