Captain Obvious

Captain Obvious and Mr Know it All make a fine pair. Imagine being stranded at sea in a very small life raft with them. Somebody would be over the side and be finding the water real soon. It's surprising that between the two of them that they're not already quoting model numbers, serial numbers, the pilot's name, his tailor's name, the squadron's home airfield, the Pantone colour of the Condor, how many kilometres that particular plane has flown, how many miles it has already made, the next date for the engines' grease and oil change, and so on and so on.
We all know men like this, and we may indeed be these men.
