Like a lot of folks, any time I kill a perk plane, I feel all warm and fuzzy inside . . . 
Most unbelievable:  Vulching SHawk (of all people) in his CHog 5 times (4 kills, one ditch) while his horde of protectors tried desperately to catch/stop me.  (I believe this brings my lifetime kill/death ratio against him to 5 / 4 billion.)
Funniest:  Flying high cap on a port capture attempt.  Goon is close when a Tempest appears.  He has alt, starts down on me.  No time to mess around and risk him seeing the goon, so I turn toward him.  Surely he will pull up.  Nope.  He receives a face-full and goes down.  I get the lovely private message:  "Lamer, why you HO when you have all the advantages.  Learn some ACM you Tard"  I think about pointing out that I am now missing a cannon, therefore he was not exactly guns-cold, or arguing about who has an advantage in that situation, but instead just throw an 
 on 200.  PM: "I can't salute you back, bro, cause you're too lame."
A little later, same sortie, here comes Tempest toward our newly captured base.  I am watching him close on my 6 -- go to try to break -- only to find in my attempt to keep him in my field of view, I had inadvertantly entered a climb and was so slow I couldn't manouver.   I just kind of flopped there.  Pushed the nose down, thinking I am far too late already.  Hear the pings and then a "bang!".  The bang is accompanied by "XXXXX has collided with you.  System:  You have shot down XXXXX #2."  Sure enough, same fella.  Throw another  and expect the PM:  None comes this time!  Land my leaking plane.
Most recent:  Some squaddies and I take off from a base where a few 262s have been buzzing about.  We see one fly directly over us, but it appears to move on.  Continuing to target, a minute later, we see a low dot on the deck as one of the 262s is trying to sneak up on us.  He comes my way since I was a little separated from the others, and I am sure because it was easy to see the bright orange N1K.  I turn toward him.  Surely he will turn away, I think.   No -- comes right in, gets a face full, and goes down.  I turn back toward target when a squaddie says he sees a second 262 coming.  I turn toward him.  Surely he will not HO after seeing the fate of his comrade . . . wrong again.  This guy was a bit better shot, but he still hit the ground first.
