My first passenger in a Cessna 152:
"hey, your house is down there, want to go down and look?" I chopped throttle, pushed the nose down and banked hard. He told me was going to be sick so I started looking for a bag. the best I could do was my flight bag. By the time I emptied it he had already started filling his hat. I went back to paying attention to flying when he decided he'd open the window to finish hurling and dump out his hat. Needless to say, that didn't work out to well. He lost his hat, and the entire cockpit was covered in vomit mist. The starboard side of the plane had a nice orange "airbrush" job once we landed. The guys in the fbo house could see it.
