Seriously, I find it to be very useful in PvP when I do battlegrounds. Sometimes newbs or people in a rush think you really died and lay off, allowing you to jump back and beat on them, much to their surprise. It's useful when pets/demons/ghouls get sicced on you, too.
Non-seriously, sometimes I 'die' in cities just to see what happens XD
Probably the most hilarious use of Feign Death occured in a BG I was in probably a year ago, Horde-side. We were waiting for WSG to start, and a blood elf hunter is chilling near by. All of a sudden he goes "Guys...guys, I don't feel so good...I really don't--AAGH!" and collapses to the ground. It was pretty amusing to envision this BE dying of a heart attack thirty seconds before the fight started.
