I've done some dumb things whilst drunk...

But nothing can beat this pair (via the BBC):

A defence agent for Grigor said: "When police were first called, they were concerned it might be a terror incident.

"But when they arrived Mr Grigor was seen wearing a pink cowboy hat, straddling an airplane with a fire extinguisher and covered in foam. They soon realised what was going on."

And I'm proud to say that this pair are friends of my daughter...
