What do Beavis and Butt-head and James Bond have to do with each other?

Over on Poppy Z Brite's blog she mentions the idea of substituting a word in a book title with the word "butt". Apparently a Beavis and Butt-head special.

I have come across this before, only it was the word "dog" and movie titles, the best series of titles being the Bond films.

• On Her Majesty' Secret Dog


• Dogs Are Forever


• The Dog Who Loved Me


• From Russia With Dog

But after a bit of this we started to use the word "beaver", but "butt" works just as well.
