A Joke Gone Wrong

At the beach with harrison, we were walking down the board walk, enjoying the nice weather. We were in third grade probably, so we were in the height of our immaturity. This was also the time where it was fun to tap people on the opposite shoulder so they would turn on the wrong side in confusion. I did this several times and harrison was to the point where he was probably getting pretty annoyed. A few minutes went by and in a sarcastic voice he says "Ha ha very funny. You're not going to get me again." I looked at him puzzled and at that moment we both knew what happened: a sea gull flying overhead had pooped on his shoulder.
