This is a rotary story... was doing "scenic flights" building some hours and had a very large woman (I think) wanting to go for a fly. I asked her to wait a while - my intention to use up more fuel before taking her up.
Her time came, we lifted off - just... manifold pressure right up there and we slowly limped into the sky.
Upon returning, I found that I could not lower the collective! Upon further investigation I discovered her copious amounts of extra body had rolled under the collective. However hard I tried pushing it out the way, I could not get it to stay away. She then abused me for "touching her up."
I had to abort the approach and explain that she sit a little more out the door to allow me to use the flight controls - as she shuffled her bulk away from the collective, I discovered the amazing effects of shifting weight and balance!!!
Small aircraft and huge people should be kept apart!
