When Wembley makes a decision in Beast Of Blue Rock... he runs the back of his head into the cave wall, and says, "Making a decision sure is..." That was just weird. Also, in Beanbarrow, I think Boober strangles Henchy just a few seconds too long. Also, in most of season 1, Boober was trying too hard to be depressing that it didn't come off as real. And of course, there's a lotta Gorg moments that I can't really list them all.
Don't get me wrong, it's still my favorite show ever.
