That is absolutely classic!

It reminds me of a story my computer serviceman told me back in the '70s. The client's mini-computer would only work as long as the repairman was on the premises. As soon as he left, the computer would crash.

It turned out that the computer was on a raised floor with the wiring underneath. As long as someone was standing on the floor it deflected enough to tighten the loose cable and make the connection.
