Usually after something scares the bejesus out of them and I kiss it on. So if my ego needs a bit of tucker then about half way through the descent I shake the **** out of the yoke, feather an engine, push lots and lots of irrelevent switches and buttons then get everything back together for the landing.
I'll only do this if I can be assured that I'll be able to conduct a greaser landing.

Seriously, twice... but that was my parents so it doesn't really count.
