What they find so funny (at your expense)

There was nothing about it that was at his expense. Don't put words in our mouths.

No, this one looks to have been completely altered by removing the whole sight. Wonder if we can get pics of the side now? There must be more to this. But still, it's not an experimental or one off...it's altered from original.
