According to someone on rec.games.roguelike.nethack, one should try
to do the following things for YAFM:


* attacking a leather or wood golem while polymorphed into a brown pudding

* entering a spider web while wielding Sting or while polymorphed into a 
  spider

* invoking your #monster ability while both polymorphed into a shrieker and 
  encased in solid rock (talk about obscure)

* getting hit by a touch of death attack while you do not have magic 
  resistance, but are hallucinating

* trying the ">" command after drinking a blessed potion of levitation.  
  Makes b!PoL's more useful, no?

* snapping your whip at the ground while levitating; especially if there's 
  an object on the ground

* trying to use an expensive camera underwater; ditto for mirrors; also 
  do while hallucinating

* looking at yourself in a mirror while polymorphed into a vampire, 
  floating eye, or umber hulk; try the floating eye case while 
  hallucinating as well

* using a cursed mirror or expensive camera

* leashing a pet with a cursed leash (ouch)

* eating a rustproof object while polymorphed into a rust monster

* encountering a demon lord while wielding Excalibur.  Funny, how they're 
  always hostile in this case ...

* eating from a non-cursed tin of spinach while hallucinating

* turning undead while polymorphed into an undead monster yourself

* levitating over a squeaky board trap while hallucinating

* praying to satisfy your hunger while hallucinating

* while being turned to stone by a cockatrice's attack and hallucinating, 
  eat an acidic corpse -- two messages depending on your charisma

* while already bloated, eating a large quantity of gold while 
  polymorphed into a rock mole
