As for dangerous, nothing really...dancing in the street and going back to the sidewalk when cars came... almost getting into an iceball fight with some creep kid at a sledding park... going fishing specifically for Stingrays from an inflatable boat...
Once I was fishing, and my grandma came to pick me up...I was not ready to leave yet so I pelted her car with dead fish and hopped on the trunk...she started driving
Then once, to mock the earlier even, I tried to jump on the trunk of her car when she was dropping me off somewhere...she didn't realize what I was trying to do, and started driving... I bounced off the trunk and hit the pavement.
I was out fishing with my friend, and we found a small burr plant. We started throwing the burrs at eachothers' clothes. Then at eachothers' heads. My friend (who will remain anonnymous) had a crew cut, and I had kinda long hair...he got a burr stuck in the middle of my head...actually 3 burrs stuck together... Well, I was 30 minutes by bus from home, and wasn't about to stop fishing, so we used his wire cutters to cut the darn things out...luckily my hair was so long that the loch of hair that was gone was unnoticeable. I drilled him in the crotch with my foot afterwards.
Then there was the time I told my friend to video tape me fishing, and I was gonna snag a log, start pulling like it was a fish, and fall down and pretend to be dragged in. Well, the hook pulled out of the log, and a 2 oz sinker came flying at my friend's head, and I fell down and smashed my elbow on a very big rock. I also once tried to put my foot on a log, and one foot on the bank of the lake, to try to net whatever might be under the log. Well the log was wet, and one of my legs went into the muddy staten island water.
The last 3 incidents were in the same trip
