I'm an alien - short story out of this world :)

Hi! My name is Zordac. When I came to Earth, the first creature I met was a human called Mr Kirk. He took me home. While he was gone, I was watching Tv and eating some washing powder - Vizir. Yummy!!! I wanted to go to see the city, so I barainwashed my dear friend and we went to the shopping mall. We met there Mr Kirk's nosey neighbour - Mrs Evans. We chatted for a while, but suddenly we had to go because of Mr Kirk's strange behavior. We came close to the Santa's sledge, wchich was full of presents. I wanted one, so I took it from the bottom of the pile. The presents collapsed, but I fixed it with my super powers. People were staring at me in a peculiar way, so I became invisible. When Mr Kirk came home, he wasn't happy about my behavior.
