Used to be a tech for Circuit City back in the day. These nasty computers were so common (mostly dust though). The one time we got a computer with cockroaches in it (i'll never forget that sickly-sweet smell) I showed my boss and he said "call the guy and tell him to pick it up, we're not keeping that in the store."

Another highlight--guy drops off his computer for viruses, it's badly infected and when i'm running scans on it I happen upon his huge porno collection. Finish up with it and call to notify that it's done. Guy comes to pick it up--except it's not him, it's my favorite professor from that semester. Turns out it's his brother's computer lol I could see the look of embarrassment in his eye, like he knew his fuck-up brother had to have some weird shit on his PC and I'd seen it all
