Steve Doocy on Fox&Friends just said that the references (lipstick/pig) had been used on their program earlier this week, so 'they were in the talking points'.
Tuesday morning, two commentators fumbled the words -- lipstick, pig -- in to their commentaries on FoxNews. One of those was Bob Becktel.
Per another poster, the other was Julien Epstein.
Dick Morris just said on Fox&Friends, the usage was deliberate. [Morris treaded it as a single utterance. He apparently is unfamiliar with the other recent uses pointed out in this thread.]
It becomes more apparent that the use of
lipstick and
pig is coordinated and choreographed. It is part of this week's talking points.
We can conclude:
"Lipstick on a pig, I'm Barak Obama, and I approved this message."
