This is a joke that was mailed to me :
Two dogs are sitting talking.
In the hazy background one can see a human walking his canine on a lead.
Says #1 dog to #2 dog
What kind of best friend
would cut off your testicals..

Say wha ???
Now I am as prone as the next person, maybe even more, to misspellings
But testicals.
And this "joke" was received by dozens if not hundreds of people, hopefully all of them struck, as was I, by the glaring mistake and yet.....I wonder.
So as not to make too big a fool of myself, I did check the dictionary; there is no word listed as testical(s).
And then I think, was it a subtle double joke that I missed entirely, like the dogs talking being sort of hillbilly kinda dogs not knowing how to spell testicle.?
NAhhh..
