I had such a weird relationship with RShack. I disagreed with him on a myriad of issues (although I have no doubt he has a great baseball IQ than mine), but we were always courteous to each other.
Anyway, after t-bag signed with the MFY's, I made a joking remark right before the season that someone should throw a battery at t-bag in the on deck circle. I included emoticons as well, so I thought I made it clear I was joking. Well, RShack negrepped me and left a lengthy diatribe about how I'm worse than Hitler and how he'll consider giving me positive rep in the future if I apologize. I neg repped him back with the comment, "are you for f*cking real!?" if memory serves. LOL
We got into a few rep battles after that, but nothing major. Although I will admit that I took some glee when he got probably the most negative rep of all-time for posting a thread telling O's fans they should be ashamed of themselves. God, I wish I could track that down again.
