i'm retired and probably watch more TV then i should (and probably is an understatement). but that being said i've see a lot of TV ads. i'm also someone who likes to play with my words. there was a trend years ago on TV to try to take the hype, and misleading claims out of TV ads, but in doing so the term they used, actually fits the classic  definition of oxymoron. and the catch phrase was:
"Truth in Advertising"...not only an oxymoron...but a very bad joke...
