Hell, I've got a few of these.
I'm a brand new LR-25 FO, maybe 40 hours in the airplane, 1400 TT, and I'm flying with this Riddle captain whom I've been warned about prior to the trip. We're positioning to Blythville, AR, to pick up some pax and take them somewhere. Ugly IFR, plane is empty, I'm flying. I'm procedure turn outbound on an NDB approach when said captain looks at me and says, "Hey, I have no idea where we are." At first I thought he was kidding, testing me, whatever.....so I pointed to him on the plate where we are, and explain it to him. He then says something like, "Oh wow, thanks. I sure am glad you knew." I almost pi$$ed myself. Over the next bit, I discovered that this guy didn't know his a$$ from a hole in the ground.
Another f-ing tool I flew with at Mesa, this guy had a voicemail on his phone that was something like this: "Hello, this is Captain (last name) with Mesa Airlines. I'm probably flying my regional jet right now so leave a message after the beep." First time I heard this, I probably called it about 20 times and played it for everyone around me, who proceeded to laugh their a$$es off with me.
