Hmm... well... depending on how you define "crazy":
Most awkward position I have found myself in:
I am playing as one of my characters named Sandy. So I got in a general RP with a runaway pup, and a male and female that didn't know each other. Mostly I was RPing with the pup, giving him food and stuff as Sandy is a fairly nurturing character. So, the female character has mate issues (control over pup), and Sandy of course is easily convinced to take her side (much more easily than I would be in the same situation). So, the pup and mate come and the classic drama occurs, and my character gets involved. Aaand some red flags showed up.
1. The male characters name didn't seem very fantasy
2. Usually people make some mistakes when RPing a fight, but this one was done too well.
3. They dropped the quote marks, he said, she said, and other RP descriptors.
So I immediately started to get worried. I said something like ((guys, this is just an RP, right?)). No response, just kept arguing. Then I really started to get worried, so I'm like ((Guys! This *is* just an RP, riiight?)) Then the male character responded with a simple "no." I was like ((Oh crap! Sorry guys, I had no idea, please don't let me interfere in your affairs!)).
The above story is a prime example of why (()) and "" are critically important for separating RP and RL!
Funniest thing:
DCs at strange times. e.g. "I will watch" *disconnects* "You will see" *disconnects*. (Disconnecting right after another character attacks me). This kindof thing tends to happen to me a lot.
Finally, in miscellaneous crazy:
One of my characters is scouting Bonfire, and considering conquering it (as per game rules, this will never happen). The ground is a bit shaky in terms of players reactions, but my character sounds like someone straight out of Civ5 (esp Ramses)!
