I’m clearing my inbox and here’s an email I sent to my manager a few months back. Definitely good for a laugh. 
Anthony (the Nav developer) is on our training room Polycom conference phone (the starfish looking thing). We all forgot he was there.
We started a GoToMeeting conference call on the standard phone. When a question was asked about development all of a sudden Anthony spoke up.
Rather than Anthony hanging up and calling into the GoToMeeting call I pushed the two speaker phones together! Definitely the first time I had two speaker phones next to each other to simulate a “conference call”.
