This is from a newsgroup alt.humor.puns which specializes in puns and word plays. Somebody wrote something about a lion that I missed, but he mis-spelled 'lion' as 'loin'. In any other setting, people would just recognize the typo (or miss it entirely) and be on with it.In this group you can bet somebody will make something out of it. Below are (highly edited) excerpts of some of the responses:

First potshot: I knew tigers were dangerous, but that bit about a large hungry loin taking down a deer was especially frightening.
So somebody else says: You ought to see what the entire porterhouse can do to an elk.
And another: That depends on whether it is a flank attack or not.
Yet another: I wouldn't steak my life on it.
And more: Gnaw...me neither.
This thread is showing an annoying tendon-cy to go off topic.
I get it! All these comments are in the same vein!
Did we hit a tender spot there?
No, he is just ribbing you.
Please, spare me!
There is more here than meats the eye.
Do you have a bone to pick with this thread?
Well done! Which is RARE for this MEDIUM.
...and so it continued...
