Conversations I've genuinely had at work:

Me: "Do you want some advice understanding that function?"
Dev: "Yeah, please!"
Me: "Get a plastic bag and some super glue..."

Dev: "I think I'm seeing the light at the end of the tunnel!"
Me: "It's just the train of mental bitchslaps coming in the other direction."
... Some time later
Dev:"You were right... "

Dev: "If the system is so unstable, how does it keep working?"
Me: "Do you see any goats in the office?"
Dev: "Uhm no... Why would there be goats?"
Me: "There aren't, now, we ran out."
Dev: "The hell are you talking about?"
Me: "We just sacrifice our own blood to Cthulhu these days, it's cleaner and we didn't have to pay to have all the goats blood and waste matter to be cleaned up. That and it was needlessly cruel to the poor goats and that is why there is no goats and despite conventional logic the app continues to work."

Dev: "So what language is the web app written in?"
Me: "You need to understand I inherited this project, I had nothing to do with it's spawning..."
Dev: "OK, that sounds ominous... How bad is it?"
Me: "Java..."
Dev: "..."

Dev: "So what's it like working on this project? What should I expect?"
Me: "You'll call your grandmother during your lunch break just to know there's a world beyond this project. You'll go home, nose bleeding and you are gonna sit in the shower and rock back and forth, holding yourself and feeling like you're suffering imposter syndrome. You'll question why you joined this team and it'll get inside your head til it's all you think about..."
Dev: "Damn man, why are you still on it?"
Me: "Stockholm syndrome, it's too late for me..."

PM: "You're such a dark person, we're not gonna find you hanging from the lights one day are we?"
Me: "Impossible, we use those industrial fluorescent strip lights, there's no cord to hang from."
PM: "That really wasn't the comforting answer I was looking for."

Head of department: "So I need to apologize, you were never meant to be left on your to manage the product on your own, it's something someone way more senior should have been doing and we reassigned him. It wasn't professional of us, it wasn't fair of us, we're sorry. Truth be told,we're impressed you've not gone mad."
Me: "I think I have. Wibble."

A card goes round work for a sick member of staff I've never met.
Me: "How would you describe her condition?"
Dev: "She said that she 'survived' the surgery."
Me: "Yeah, I'm not great at being appropriate but even I think writing 'glad to hear that you are not dead' in a get well soon card isn't the done thing."
