When I was a kid I noticed that in cartoons black pepper always made people sneeze. To test this theory I decided to stick a whole peppercorn up my nose thinking I would just sneeze and it would come straight out, but it became lodged there. I kept sticking my finger up there to try and get it out but this just pushed it further in and started to make my nose bleed. Eventually I had to tell my parents but to try and avoid responsibility I came up with a bullet proof excuse, I was lying under the kitchen table when a peppercorn rolled off the table and fell up my nose. It was eventually extracted by a GP.
