The Fambly Bunch Theme Song (to be sung to the tune of "The Brady Bunch" theme song) by Yours Truly
Here's a story of a manly lady
Who was bringing up three very lovely kids
They had hair of black... like their Mama
The youngest one sure did

It's a story of a man named Joseph
Who was bringing up two pets and a child of his own
They were insane... living altogether
'Cuz they were all alone

Till the one day when a pet said "Joe's our Papa!"
And they knew that it was more than just a hunch
That this group must somehow form a family
That's the way we all became the Fambly Bunch!

The Fambly Bunch!
The Fambly Bunch!
That's the way we all became the Fambly Bunch!
