How about a flight of 4 cleared onto hold in front of a DC-9 on short final. Luckily the DC-9 crew saw the 4-ship and executed the go around. Everyone gave the flight lead c**p for not seeing the DC-9 as he was waiting for t/o clearance - the common theme was that he had his mirrors positioned so that he could admire himself rather than see some big airplane trying to land on his flight.
