Once when my brother and I were only about 10 or 11 I really annoyed him.
He was sitting in the loung-room reading a book and my crazy sense of humour gave me an idea for a bit of fun. I was inside a side room in a corridor leading straight out of the open door of the main lounge and I opened the door up a crack. Having a bubble blower tube in my hand I started to speak through it so that my voice was all distorted. And this is what I said.
"Hello. I am the Invisible Man. Isn't it a lovely day?"
After a brief pause I said, "Hello. I am the Invisible Man. Aren't you going to say hello to me?"
Another pause. Then again I said, "Hello. I am the Invisible Man." pause then adding, "You sure don't have much to say do you?"
Then my brother appeared at the door and said "I knew it was you Martin."
After he stomped off I stood there for awhile. I felt like a little more fun and staring at some of the stuffed toy animals in the room I was in, I had another idea.
I took a monkey doll and stuck it out into the hall from shoulder height so that it was hanging up in the air, where he would be able to see it through the lounge into the corridor. And this time I began to speak in a high-pitched squeaky voice without pausing as all.
"Hello. I'm Mary the Monkey. How are you? Well it's such a nice day, I thought I'd drop in and visit you for awhile. Find out how you were going. I hope you've been keeping in good health." And so on. And so on. Until finally he came charging into the room, took the monkey doll of me, threw it on the floor and stormed back out again.
I was laughing as much as I am now typing this and I thought that was enough fun and went to find something else to do.
