My mate cast a spinner, didnt see it splash, just heard, SSSHHH*t. he turned round to see the spinner stuck in our other mates ear. Hospital to get it out.
I also saw a guy with a lump like a golf ball on his forehead, He got his line stuck up a tree, got the line as tight as he could, and pulled. SMACK the lead flew back and hit just above his eye, he was a lucky lad.
Don't ask me how, but heres one for you. But its not casting.
I went to put a boilie on a needle, and ended up with the needle stuck under my finger nail upto the first knuckle, dont ask how i managed it, because i dont have a clue. Hospital to get it out.
The funny thing was the other anglers, when i asked them to look after my gear while i went to hospital, and showed them the needle stuck in my finger, they all turned away, and one was almost sick. I lost 4 hours fishing that weekend.
