ABC ON CBS: "ALT-BARNEY CONUNDRUM"

It looks like the Super Bowl advertising gave us more than just a bunch of new TV characters (personal favorite? The robot in the Pentium blipvert.) A CBS promo for 'How I Met Your Mother' showed Barney flashing a sign advertising his Lothario ways. But this differed from the one seen on the HIMYM episode that aired the following night:
The easy splainin? Even though Super Bowl 44 (screw the Roman numerals!) was televised, we were still seeing the actual Super Bowl game. The gang back at Ted's apartment watched the televersion of that same game. And so the difference between the commercial and the telecast within the show have to be considered from alternate dimensions.

The CBS promo has to be the one Super Bowl blipvert that has to be relegated to an alternate dimension. The rest of them can find a home in Earth Prime-Time, the main Toobworld.

The CBS promo could probably fit right into the "promoverse" where many of the USA Network blipverts combining their shows ended up....

BCnU!
