We've all been there, don't worry about it!
Once while flying a Cardinal RG with autopilot problems, thinking I was holding down the autopilot disconnect button (label worn off), The whole area heard what I thought of the misbehaving autopilot. On another occasion, while right seat in a Cheyenne, and having just perfectly read out a checklist to my captain, ATC replied that I had done a good job of reading the checklist, but they did not care. Wrong button again!
This is one of the flyings aspects where the saying applies well...
There are those who have, and those who will...
Have a laugh about it with the rest of us, and fly on!
