In a morning 'stand up'.. (SM = Scrum Master, PO = Product Owner)

SM: "Sprint item 42399 ... Did you work with Ken on getting the price service ready for deployment?"
Me: "No, I worked with Dave on the service bus queue changes. Its there in the notes"
SM: "Ha ha...no...right there...it reads working with Ken."
Me: "Those are your notes. You re-assigned the ticket to yourself yesterday."
SM: "Oh...um...you told me you were working with Ken when I asked."
Me: "I'm really sorry, I don't remember you asking or me saying anything about changes to the price service. All the documentation I have is for the service bus."
PO: "I'm so confused, Ken was pulled off another project to work on the Price service for you guys."
Me: "I never talked to Ken, I have no idea whats going on. Did you tell Ken he had to make changes to the Price service?"
SM: "No..I never...um...well....yea...this card was blocked and the service needed to be approved and deployed."
Me: "Ken's changes were for the purchasing service two weeks ago and already deployed. The card is already marked as Done"
<PO rubs his face>
PO: "Good god...do I still need to be here?"
Me:"Um...no? Sorry?"
<PO walks out>
Me: "What changes did you tell Ken to make?"
SM: "Whatever the card says...see the price service."
Me: "Scroll down...see..price related to the service bus, not price service."
SM:"Work with Dave on getting this card closed, OK?"

Good fracking grief. Your ego is so brittle and so eager to look like a boss.
I did my job, you fracking kiss ass. I'm fracking sure when you re-assigned the ticket you told my boss you "had to" because I was falling behind in the sprint.
