Good question, I personally didn't mind all that much. Sometimes I will do something like that, but it's always with the line from the episode that I'm posting. You didn't post an actual line from the episode, therefore weren't part of the list. Somebody else chimed in doing something similar, they were not included either. You weren't singled out.
If a lot of interruptions were to be made in future threads, I can't speak for anyone else, but I would not be happy about it. I think you're line was funny, but don't run that into the ground.
I've inserted something goofy from time to time as well. Sometimes you just can't help it when the opportunity avails. Sometimes there's a line or event that in retrospect is so dorky that you can't help but make a comment on it. I wouldn't want to see a whole lot of them either in the main episode thread as LeadHead
is saying, but when we go to do something after the episode while we're waiting for the next one, I've always felt the board was open and hit whatever you want cause it's not official. Hence the bit from above.
Does that make sense or have I gone off the deep end? (again.. lol)
