As for "like," "you know," and their ilk, I've been known to treat them as actual content
. This startles the speaker to no end.
In fact, many seem not to be aware of these phrases in their own speech until said phrases are responded to.

This has happened to me two or three times at the large dog park near here, my best source of interaction with people not previously known to me. No doubt I sound strange to them when we start, but by the "What?" point of the interchange, they're definitely paying attention to what they are saying, since *I* clearly am.
