"Murphy Brown Lied To Us"
“I'll spend the rest of my career behind this desk,
trying to lure ALF back to television.”
"ALF" is an acronym for "Alien Life Form". It served as the alias for Gordon Shumway, who hailed from the planet Melmac.
From the line's phrasing, it could be that Jack was speaking of Alf as a real "person", which he is in the Toobworld Dynamic. Jack wasn't talking about the sitcom that introduced the furry cat-muncher, but rather the talk show which Alf once hosted.
The Melmackian became a world-wide sensation after the military made an unsuccessful attempt to capture him. (So much for "covert ops"!) Because of this fiasco, Alf became known throughout all of Earth Prime-Time, which is why he was offered the talk show.
