May as well add this in too...
Outside flying I sometimes deal with a yearlong uncurrent PPL with about 150 hours. The amazing thing about this particular PPL is that he's one of those rare ones who knows everything there is to know at such an early level of experience. For that reason he will not stand being corrected by anyone of any experience level, and rightly so. He enjoys giving me lectures using the most painful nerve-twanging half-baked terms and facts, and any attempt offer him some furthering or angling-conversation-toward-the-physically-possible is cut off with a "Yep, yep" and change of subject.
I usually avoid flying discussions with him (such as: now did you know a jet engine has fans in the front AND back? The back one's for cooling or a similar purpose, it gets extremely hot in those things you know, hotter than a car engine, you wouldn't want to stand behind it). But, recently, he dragged me into a lecture about stalling, and he introduced me to this checklist you do before practicing it, which isn't written down because you can just call it HASELL to remember it.
"Height, Altitude, Stress, Elevation, and I forget the other two..."
