I would have to say at least five. (1) Numbskull who gets bogged to get the ball rolling
(2) Knock-knock who tries a snatch extraction with a chain without the forethought to "just dig a little"
(3) Spoonman who thinks his rig will get er' done and only manages to help bog himself and #2
(4) The ambulance driver who has to come pick up the bits of injured bystanders but cos' he isn't allowed to lower his pressures gets bogged too! (Assuming its another Toymota)
(5) Ambo driver number two to come help out #4 with the cleanup and of course perform a safe recovery.
(If only #4 & #5 were replaced with the one Datto driven by someone with some brains who could have stopped it all from escalating -----or maybe just stood back to watch this deathly comedy of errors!)
