Input: Text: i was hanging out down at the beach with a couple friends today. we had my buddy's raft out in the water with a few beers. i was standing in the water when i finished my beer and i decided since i was close enough to the shore, i'd throw my can onto the shore to pick up on my way out. i filled it with water to have enough weight to chuck it a ways in.

here's the problem. another friend did this a couple years back and learned to throw with the bottom facing his fingers. why you might ask? because the open mouth of a can is sharp as fuck and will slice your shit if you throw it hard enough.

sure enough, as soon as i released the aluminum devil, i felt a sharp pain in my finger. i looked down to see a considerable amount of blood and a nice skin flap. i immediately went home and called the doctor's office. 1 hour later, i now have the first 3 stitches of my life, a pain in my dominant hand index finger, a tetanus shot and a life lesson.

i guess the good thing is my last tetanus shot was 10 years ago so i was due.
