Punched myself in the breast.......

..........it hurt A LOT; I don't recommend it.

I was making pizza for my family this evening.  The passata, that I needed for the sauce, was in a small tin, shrink wrapped to 11 other such tins, in my kitchen cupboard.  The considerable force with which I was pulling on the plastic wrapping was transferred into the punch I gave my left tit when the wrapping finally gave way!!

Ouchie!!!
