Saturday night, “Saturday Night Live” opened with this sketch.

Yes, that’s a comedian, pretending to be President Barack Obama, making jokes.

Yes, that was stating the obvious. Unless you’re CNN, then you decide that these jokes are worthy of a fact-check.

Do you remember CNN “fact-checking” when Tina Fey/Sarah Palin falsely stated (for effect) that she could see Russia from “her front porch?” No, I don’t either.

All of this would be merely amusing, if it weren’t for Twitter, which now has a robust online snark for those who search for the hash tag #CNNFactCheck. A sample from The Wall Street Journal’s James Taranto:

@DefiantKembro 'El Nino' is not Spanish for "the Nino" #CNNFactCheck

@EnasYorl "Wayne's World" was not really a public access cable show. #CNNfactcheck

@ArielAkiva The superfans were not actually having heart attacks. #cnnfactcheck

@thecomeback After checking every river in America, we have not been able to find a motivational speaker living in a van. #CNNfactcheck

@jeffdobbs: Over half of Saturday Night Live is NOT ON SATURDAY NIGHT for Eastern time zone. Outrage. #CNNFactCheck

@jkfecke In fact, Blue Öyster Cult never included a cowbell player named Gene Frenkle--the musician didn't exist. #CNNFactCheck

@mikehassinger: This just in: "Toonces the driving cat" not real cat, can't even DRIVE! #CNNFactCheck

Other ones that have appeared since Taranto’s post went online:

• @IronyNow Motivational Speaker Foley's Van Positioned by Creek, Not River #CNNFactCheck
• @JimmahIceLLC Breaking: Church Lady not actually lady. #CNNFactCheck
• @IMAO "CNN now reporting that it was not really a large bee and merely Jon Belushi in costume" #CNNFactCheck
• @vadoug: Jane Curtin was NOT ignorant. #CNNFactcheck

Heck, she’s probably not a slut either.

But CNN might want to check that.
