Sleeper's Madness

When some fuckface wakes you up and you try to go back to sleep for a long time, all the while becoming progressively angrier and angrier until you throw back the covers and get up in a fit of rage, thereby abandoning any attempts to salvage sleeping in on your day off from school/work.

Guy 1: "Doctor, this morning I stabbed my roomate in the side of his throat with a harpoon after he woke me up for the fifth morning in a row, ruining yet another morning's rest."
Doctor1: "Dayummm nigga, looks like you dun got yoself one o' da worst cases o' sleeper's madness I ever dun seen in my mo. fuckin. LIFE!!!!"
MedStudent1: "I concur, maybe one day I can clean up my wife's gambling problem and get my finances together to pay off my debts and cure this horrible disease."
Doctor1: "Nigga you best be frenchin' wit me, cuz you ain't neva gonna do dat shit, dis disease be fuckin' INCURABLE, and I would know, I graduated from Harvard Med, top o' ma mofuckin class."
