As a young man at college, I used to sing this song on coach trips returning from hockey matches. I recognize most of the verses in the same form or slight variations in the threads above. A couple of the verses I sang were:

In the next cage ladies and gentlemen is the F-f-f-fuffer-mouse.

Fan-tastic, in-credible, im-possible, what the f*cking hell is that?

This animile ladies and gentlemen lives in the Say-har-ay desert where it travels in groups in Indian file. The last one in the line disappears up the arse-hole of the one before until there is only one left who says, "Where the f-f-f-f*cking hell do we go from here?

The Camel

This animile also lives in the Say-har-ay desert where it can go for weeks without drinking water, living entirely on sand.
Hence the pyramids!
