Software Projects Puns

For my job in a software company we have to record a conference call with the developer and my QA team whenever we push a new project live. During the call there was a train in the background which was pretty loud coming from the developer who is named Trey. After we had finished testing i said: "Hey, did anyone else hear that? What was that?" My boss who was in the call said: "Yea i did, it was a train i think." I let the silence hang for a bit and said: "Are you sure? It sounded like a Treyyyyyyyain" Immediately heard multiple groans and my boss says: "Ok i'm done" and leaves the call, quickly followed by everyone else.
