E2 user actions

I'm not exactly sure what to call it, but you've all seen it. Those little random actions that appear next to user's names in the Other users nodelett. Yea, that's what I'm talking about. (if there is already a node out there about this, please point me to it)
They first appeared on February 9, 2001. I have spent wasted a couple hours of my time observing them, and this is what I have noticed:

They are random combinations of a set of actions and nouns in the format: USERNAME ACTION NOUN
Through my observations, I have noted the following actions and nouns that are used in these random phrases:

Update:
These little user actions seem to have mysteriously dissapeared several days after their first existence. The preceeding has been identified as the "Spy on other users" User setting by the following write-up. (was originally pointed out by gnarl)

Also, I'm sure there's more than that, so feel free to /msg me ones that aren't listed now.
