I.D. this cartoon? "John & Mary"

[Anim8rFSK]

A friend IM'd me this. I don't have the slightest idea what he's
talking about, so I told him I'd ask here:

Hey, I have a challenge.

I'm looking for a specific warner cartoon� can't find it....

It's a cartoon that spoofs the Stan Freiberg skit, "John and Marsha",
for the cartoon it's "John and Mary"� Oh John! MMMMAAAARRRYYYY!!!!
JOHN!!! MMMMAAAARRRRRYYYYY Remember this?

Anybody?
TIA

It's the show 'Defiling Gravity' would be if DG had more regulars,
fewer abortions, worse writers, and no budget for lighting.
Remember, you can't spell "disgust" without SGU!
