Holy Crap! I never noticed how much Worf's ideas and suggestion got shot down during the series run of Star Trek: The Next Generation, but damn! No one listens to the poor guy! He just gets denied, shot down, rejected, scoffed at, laughed at over and over again. Despite the lack of confidence that crew members obviously have in him, he still manages to stay cool and calm through every shut down.
Here's a great video compilation video showing every moment that Warf is crapped on by everyone on the enterprise. This is absolutely hilarious, I laughed harder and harder the more it went on. The video is over 15 minutes long, but it's worth watching. Enjoy!
