Help finding a poster (Demotivator?) -- Badly needed!

[SeekHer]

I saw a poster here (or the other site) that I wished now that I had downloaded.

It was either a line drawing of a pair of jackasses humping away or a pair of dogs at the top of the poster.

Next was a line drawing of most definitely a bull depositing a pile of shit.

There were two versions--The first just had the red circle with strike through over the whole picture and the second had captioning at the poster's top "NOT THIS" and at the bottom "AGAIN".

I'd also seen it with photos substituted for the line drawings of the Jackasses and Bull.

Submitters will be thrice blessed for their endeavors.
