stupid me, can't change a battery?

Don't feel too bad. Yesterday I went to my local Lowes hardware to get a new staple gun that also takes brad nails. I laughed when I saw the arrow on top of the gun that said exit here:) Of course the first 9/16 brad that came out went in just under my pointing finger:) I was holding it backwards when I (pulled the trigger). It took me about 5 seconds to figure out why no nail came out and where it went:) I looked at the arrow and it pointed to my hand:) Learn from your mistakes and continue on!
