and now for something completely different 

A phrase coined by the British comedy troupe Monty Python. It is used to signify the arrival of something that is, indeed, completely different from whatever had been going on previously.

See also: Pythonesque comedy.

The llama is a quadruped which lives in the big rivers like the Amazon. It has two ears, a heart, a forehead, and a beak for eating honey. But it is provided with fins for swimming.

Llamas are larger than frogs.

Llamas are dangerous, so if you see one where people are swimming, you shout...

Look out, there are llamas!
