get a really anoying alarm clock and just hit snooze when u wake up. Then go take a shower. I used to do that to my roomate every morning. My other roomated didnt care cuz it was worth watching the other one freak out. We used to also have parties in our room every night he had to get up early. He started wearing earplugs to bed after a while. We were making as much noise as possable with firecrackers and breaking shit and couldent firgure out why he was still sleeping.
