I saw this impressive demo years ago on a B-742 in SIN.

That's probably the most familiar story with these inadvertent widebody gear retractions prior to taxi. In the 747 incident I saw an Airbus pin was used to secure a Boeing nosegear. And, as a locally made modification, a handle was welded to the pin to snag on something when the gear doors started to open. Out went the pin and up went the nosegear. The gear doors were being cycled to check the rigging or check for leaks according to the ground engineers.
Here's another more recent incident in SIN:
A Singapore Airlines Airbus plane collapsed on its nose on Sunday morning at Changi Airport.
The nose gear of an Airbus A330-300 "retracted while the aircraft was undergoing a landing gear system check," the airline said in a statement.
"There were no passengers or crew on board at the time," Singapore Airlines said, according to the Associated Press.
