vice grips to the eye

today i was working on the exhaust still went to put the flange bolts in and realized the were the wrong thread the guy at the store gave me the wrong ones so went back and got the right thread and went to put them in and realized that the bottom threads were the nuts go were to short so i had to pack like 6 washers and it still has a small leak in it but i said o well cuz you cant hear but if you put your hand over it you can feel it bu anyways i went to take the bolts out after i realzed they needed washers and i had to hold the bolt in place so i locked vice grips onto it and hit it with a 3/8 impact to take it off and the v/g hit in the eye it hurt so freakin bad but o well i found it kinda interesting
