Not really a stupid client, but he'd gotten a BAD_POOL_CALLER 0XC2 message.... blue screened while in Recovery Console. I gave him the bad news that his OS was hosed, his data was gone:
Client: "Maybe if I leave it sit over night, it'll work in the morning."
Me: I doubt that...
Client: "The little electrons are tired... they're just tired..... "
Me: Offered the number for a data recovery company.
Client: "Well, I'll let this sit over night and maybe the magic faeries will come in and fix it for us.... I'll call you back tomorrow."
