First time eating sushi.  Covered the entire California roll in Wasabi.  My family decided not to warn me and get some amusement out of it.  This was back when I was just starting to try new foods, and so my strategy was to just pop it in as fast as possible and start chewing.  And I did just that.   As soon as it made contact, I felt a rush of heat go through my mouth.  I was still on autopilot, so I got about 3 chews in.  Each one felt like I was nawing on the end of a taser.  Spat it out and my face felt like it melting.  Tears were flooding frim my eyes.  They felt so cool against my red skin, that they gave my cheeks a burning sensation similar to frostbite.  My mouth felt like I had just used battery acid as mouthwash.  I was disoriented by the strength of the wasabi, and I searched frantically for my water.  I finally found it and began pouring it down my throat.  This asperated my throat, causing me to gag.  So I just sat there choking on my own throat, while my family laughed at me.
