He probably thinks 'if anyone ever finds out about my perv picture collection,  Ill just say someone else used my computer. Haha. Im a super genius. They'llnever figure THAT one out. Ha!'

Later, down at the police station...

Police: what was his name?
Roy: I don't know.
Police: why did you let him use your computer?
Roy: he said it was an emergency.
Police: did he say what the emergency was?
Roy: No.
Police : and you gave him your sign on and password?
Roy: uh... yes, I guess. Maybe. I don't know how he logged on.

Roy now begins to sweat.

Police: OK, so the first image was downloaded on August 2nd, 1997. Was this the day the unknown man used your computer?
Roy: Yes! Obviously!
Police: Ok, you have 1,546,805 illegal images downloaded over the corse of 26 years, the most recent was downloaded yesterday.

Roy: sweating profusely,  nose running with snot, tears welling up in his eyes, slight tremor pervades his entire body. Jaw clenched, blurts out: "YOU HAVE SMALL HANDS, GIMMICK!

Police: Are we going to have to go through this 1,546,804 more times?
Roy: blank stare, completely dumbstruck.

Police: OK, who is Paul Graham and why do you have pictures of his cock?
Roy: ITS A SICKNESS.  I NEED HELP! ITS NOT MY FAULT. I CANT HELP IT!
