I was in the fifth grade. I had been feeling under the weather all morning and my stomach was a little upset. I would have been OK to just shake it off and work through the pain if I had been left alone, but I sat behind a good friend of mine and he was talking to me all morning. I had asked him to leave me alone a few times that morning but being 10 years old, of course he didn't. After about an hour of this, I was starting to really feel like something was about to go down... or come up rather. I was pretty sure I could make it to the bathroom, so I walked to the back of the room to my teacher's desk to get a hall pass. What I had planned to say was this, "Mrs. James, I'm feeling sick, can I go to the bathroom?" What I managed to get out was, "Mrs. James, I'm feeling.... BLEEEARGH." I projectile vomitted ALL over her desk, papers, and filing cabinet. Luckily I didn't get any on her, but man did I feel better after that. I got sent home after that, and the next day everyone said that my puke had stunk up the entire room. Definitely my worst hurling experience to date.
Also clogged up my sink after eating a huge breakfast burrito for dinner one night. Had a few too many of the Downtown IPA. I was drunk as I could be at 2AM trying to unclog a sink with a disgusting bile/water/sausage chunks mix a few inches deep in it. I learned not to drink heavier beers in large amounts after that one.
