Mistaken Identity
My father always had a habit of getting ahead of the group whenever my family (consisting of myself, my sister, and my mother) was on a hike or going somewhere. He quite often would get far enough ahead that we lost sight of him, and then would hide off to the side until we walked by. Then he would jump out and scare the living bejesus out of us.

When I was about 11, we were visiting Australia. I don't remember where we were going, but my father walked down a narrow passageway. My sister and I were behind him by a bit, so as we approached the entrance to the alley we let a man who seemed to be in a bit of a hurry pass us.

Unbeknownst to us, my father lay in wait at the end of the passage and as the man exited he was confronted by my 6'4", 250-pound, scruffy-looking father jumping out at him and yelling "YAAAARGH!"

The man jumped away suitably startled while my sister and I burst out laughing at my father's case of mistaken identity. Luckily the man quickly noticed the two little girls laughing hysterically and figured out that we were the intended victims. He continued on his way acting as if it hadn't happened.

hah. Risky.
I remember my Uncle aunt and cousins staying at our house once. We were all watching Salems lot on TV, getting pretty creeped out. I must have been 15 - 16 at the time.

I went into the kitchen to get something to drink. As I walked out of the kitchen, my Uncle was lurking in the hall, and shouted 'Arrrrrrr' at me. I dropped the glass I had in my hand, both my hands went straight to his throat and I threw him up against the wall behind him, and kneed him in the stomach.

He was on the floor coughing and trying to get his breath back before either of us realised what had happened. I don't really know what made me react like that.
