Some help with an introduction?

For my English short story, I have decided to aim at comedy. OK, it's horrendous (laughs). I got the idea from Charlie The Unicorn. It's about when the internet and real life combine. Fat people falling in slow motion, Rick Astle will make a comeback! The title is keeping secrets. The weasle (he can talk BTW) has a dream that the internet is going to leak into the real world. He knows the secret and everyone suspects he knows something. (haha) Somewhere along the way, it starts raining chocolate, and Rick Astle comes along singing, and everybody screams and runs away the weasel burns down Hot Topic because he suspects that the goths are using magic powers to make the internet leak out with their voodoo. One problem; I can't think of an introduction! Can somebody please help me? xxxx
