Discussions of almost any kind are boring when everyone is too serious and strict about keeping to the topic. I like serious discussion, but I don't like it being serious all the time. Sometimes I make a super lame joke because the rest of the discussion is a bit dull/slow, but usually I make good jokes.
EDIT: As an aside, I wouldn't have teased you if I thought it was a typo. I thought you had just screwed up the expression.
