trapped in my gilet

I managed to get the zipper on my gilet well and truly stuck this morning.  Just to add to my difficulty I have put my back out by foolishly lifting an unwieldy, heavy pack of laminate flooring.   
Anyway, after me sinking some strong painkillers, Ed managed to wrench the ruddy thing off me, whilst stopping every now and again to take a string of pictures.  
As you can see I got the most chronic attack of the giggles during the procedure.   
Ed has also now unstuck my zipper with a combo of washing up liquid, a pencil and brute force.
I think I need a lie down.
