To be fair, the one job I had where the boss made a habit of riding up front, I didn't last long either. But three good ones:
One of my first flights with him en route, expecting a right turn at some point, ATC gives me a left turn. As I'm reading back the assigned heading I initially spin the bug right but before finishing the read back I'm already turning it back left. He lost his mind thinking we were going to die. Airplane never even nudged to the the right (we were still in NAV). I knew I had a winner there.
Cruising along in the neighborhood of FL260 in the middle of the summer and not a cloud in the sky, he figures out how to tell temperature and that it's below freezing. Again, he starts freaking out because I don't have the anti-icing system on. Apparently someone had told him about 'pilots getting in trouble with ice in the summer because they don't realize how cold it gets this high'. I tried to explain the concepts of visible moisture and that you need some form of water to make ice. Gave me a weird look like I was lying to keep my job. Many of our flights went this way with a very quiet rest of the flight.
Best one, on decent into a major city, I hear on the radio that there's parachute jumping ops ahead. Sure enough, when we get close, the Caravan with the jumpers are called out to us on the radio. I responded that I see them. He had his headset on but I guess he was tuned out daydreaming or something. We were close enough to actually see the first person jump out:
Him: "OH MY GOD!!! SOMEONE JUST FELL OUT THAT PLANE!!!! DID YOU SEE THAT.... OH MY GOD THERE'S ANOTHER... OH MY GOD THIS IS TERRIBLE... AND ANOTHER... JESUS CHRIST SOMEONE HAS TO STOP THIS...!!!!!!!"
This goes on for a minute or two of his screaming as each person jumps one by one and his face is in shear terror and he can't figure out why I'm laughing so hard.
I'm laughing so hard there's nothing I can do to slow him down, much less explain what's going on. I have tears coming out of my eyes so bad I can't even see the instrument panel.
