Yes, Radio Shack is one of those things you can get a cynical pleasure out of having contempt for or making fun of. Walt's story is a clear example of what I mean.
Now, that brings up another point. There is absolutely nothing wrong with putting a preposition at the end of a sentence if it makes the meaning clear. That non-rule must have been suggested by some old fuddy-duddy who couldn't find anything real to gripe about. Look how absurdly cumbersome the above sentences become when one goes to all the trouble of not placing the preposition at the end:
...things for which you can get a cynical pleasure out of having contempt, or of which to make fun... anything real about which to gripe.
Another mistake I see all the time, even in professional writing and ad copy where the author should know better, is the use of "it's" to show possession.
It's is a contraction of
it is and nothing else, and should never relate to that which belongs to
it. That should be spelt
its without the apostrophe, just as we don't write
hi's or
her's (I have seen people use the latter, as well as
your's,
our's and
their's).
Another one is the misuse of the apostrophe to show plural, often seen on signs: Fresh Oyster's For Sale, Used Car's.
Then there is current flow.
How about DC current, AC current and the i.f. frequency? ...Well at least that's not as bad spelling
ham (as in ham radio) all capitals, and/or leaving the
radio part out of the phrase.
