This happened 2 years ago in my previous job. It was usually myself and my 2 other co workers (1 guy and 1 girl). It was April fools and I made a lame joke about being late because I needed blinker fluid to my guy co worker.

We both just ran with the joke and expanded on the flux capacitor, both of us obviously joking around….then my other girl co worker chimed in…

“What’s blinker fluid??? Does my car need it!?” She said it so concerned.

Me and my guy co worker looked at each other like…. Should we keep it going?

Then we kept talking about how we change it every month and it’s so hard to find.

So I sent a link to our work chat which is a fake website that has the blinker fluid.

She started freaking out and saying she’s never changed it….

She gets up and CALLS HER BROTHER (she’s the only girl in her family and usually her brothers take care of her care maintenance ) and starts bashing the brother like YELLING at him why he’s never changed it and he doesn’t care for her.. the brother was just like “hold up what are you talking about”

She leaves the room and keeps on yelling to her brother.

Me and my guy co worker just crack up so loud but felt so bad…..

When she returns she said her brother will do more research and take care of it…..

The next day she comes in I HATE YOU GUYS! and she didn’t talk to us the rest of the week…

I still bad

TL;DR: blinker fluid inside joke turned into mayhem on a poor innocent sibling
