When I was younger I had someone throw a paper bag with something in it at me. It was like the leftovers of someones lunch or something. It was pretty heavy and left a nasty bruise. I've also been shot by airsoft or bb gun before. What I really hate though is when people drive up right besides me and yell at me. It always startles me and gets my heart racing for the next few minutes (I hate the feeling of artificial flight or fight heart rate jumps). BTW, I always rode in the bike lanes going the correct direction and used hand signals and I'm a very defensive rider so I doubt I pissed off any of these people.

Since I've recently started riding again, I'm going to come up with some imaginative ways of getting people back next time this happens to me.
