More a crowning campaign of funny, but Commodore Acaltha's mission in the Jericho system qualifies, from the sheer amount of insane tactics and ludicrous stunts they pull. Things such as:
overloading the Minbari's communication systems with everything from Klingon Opera to 20th Century J-Pop
playing a shell game with holographic decoys and real Klingon ships to sow confusion among the Minbari ranks
and after these and many more tricks, the final slap in the face: surrendering the Jericho system to the Minbari after an entire month... only to reveal that it had already been evacuated before the first Minbari ship ever arrived in system.
