Up until recently, I had never heard anyone pronounce GIF as "JIF". It was always "GIF". I'd heard Ethernet pronounced like ethanol, and they're always the Linux pronunciation debate, but I'd never heard anyone called it a "JIF" before. But then this new hire at work starts calling them JIFs, and I couldn't help thinking about Jif peanut butter

Then, later, we're in a meeting, and she's talking to the UI chick, and she says "JIF". And the UI chick says, "They're called GIFs. JIF is a brand of peanut butter."

I almost had to leave the room.
