Martians were arriving at Los Angeles airport at 4 a.m.

One young man with psychosis told the friendly but untrained support staff that Martians were arriving at Los Angeles airport at 4 a.m. the following morning. So they went. When the aliens failed to materialise, he said that they must have got the date wrong – I suggest this was the first time he had ever been taken seriously – his ‘consent’ mattered.
