At the end of the show the logo for UBU Productions shows a dog with a frisbee in its mouth and you hear a voice.
Does he say "sit ubu, sit" OR "sit,boo boo, sit".
Please help.

Sit ubu Sit.....good dog

is what is said at the end of family ties, much the same as for Spin City.

Ubu the dog actually belonged to Gary David Goldberg, one of the creators of both Family Ties and Spin City.
