Funny story:

We were going through Sprint Planning on Monday. We got through all of the tasks that we knew we had to get done, then we started going through the backlog to see what we could pull forward.

The guy running the meeting (who's not actually a Scrum master, but whatever) get's to a task, reads it aloud, and goes, "That doesn't ring any bells. Brian, it's in your name, it says it's from May, do you know what the status of this is?

Brian reads through it for about 20 seconds before saying, "That date says it's from 2017. I don't think we need it anymore."
