concept of presentation

hi, tension of presentation is getting on my nerves now.... its 5.12 now and still its building like a laxmi mittal's building..... and now there is no escape window for not doing the presentation things....so i have to manage it any how.. to make presentation ( 10 min joke ) is a really skilly thing to do. u have to decide what u wanna joke and people should not laugh at ur joke.... if u r able make the proffer believe that ur joke was serious then u will be getting marks of great heights........
