One Time I Laughed Real Hard

I've laughed real hard lots of times but I can't really remember how I came about to laughing except for one. When I was in 4th grade, so around more or less 9 years old. I was at my friends house, he lived across the street and his neighbors was another friend of ours. The one's whose house we were at had a "scary" mask, more hideous if anything. We were outside in his front lawn and he pulls out the mask and starts chasing us (now that I am older it's not really funny but then it was just plain hilarious) and there was this wooden power line pole. And me and my other friend ran across the street just to get away knowing he wouldn't cross. But he ran towards our voices and ran right into the pole. Me and my other friend could not stop laughing, it was like a scene from a comedy movie, he ran into the pole and fell backwards to the floor. He took off the mask and starts rubbing his head and said oww. Maybe it was the fact that karma got him back real soon or because we were young enough to think slap-stick was hilarious but we could not stop laughing at him for crashing into that pole. I was crying from so much laughter and my friend was on the sidewalk just holding his stomach from so much laughing while my other friend just stared at us from across the street sitting on the floor rubbing his head.
