Our school had something like an 'Afternoon care' for everyone under 8th grade where you basically stayed in school, ate and did all your homework for children whose parens worked long hours.
So, during our free time there a friend and I decided that it`d be really cool to get into the gym, take these weird sticks with styriofoam around the tip and play "Jedi" - essentially fighting with this things while imaging some epic Star Wars Soundtrack in the background. We did this for about 15 mins. when I trippded and fell backwards landing on my back. My friend thought its a great idea to exploid this slip and thrust this stick right into my face shouting some stupid phrase (Probably among the lines of "Now you're done for" or "Hasta la vista baby")... the back of my head bashed against the floor and shortly after something felt weird in my mouth.
Turned out, he nearly bashed out my upper front teeth. Later in the hospital they said that each tooth was basically dangling from only one nerve each (and several years later they said that I was lucky that I didn't need a Root canal treatment).
The punchline: this happened on the 23rd of december so I could only eat soft white bread without crust at christmas eve. (and my entire mouth hurt throughout the winter vacation).
Though honestly, we could laugh about this when we saw each other in school again.
