It was fun with 3 pilots, you usually had someone you got along with, and the two of you could gang up on the 'other guy' to pull some practical jokes on him, especially if he was a hard over tool. Usually it was the Cap/FO pulling the jokes on the new hire Engineer of course, and they would sometimes enlist the FA's to help mess with you, so you had to just roll with it, knowing you were going to be goofed on most of the time in the cockpit, but on the layovers they usually took good care of you.

Not as much fun now with the 2 pilot cockpits for new hires, and when one of you farts, there's just nobody else to blame it on! No plausible deniability at all!
