In this video I was tied up and thrown into my own gunge tank for questions (I guess I deserved it for making the questions so difficult) and Lady Muck put me through the same impossible questions as I had dished out to them, and likewise the trick question was changed so I got it wrong and was gunged, then stripped down and gunged again.

This time I've lined up my cheerleaders for a simple intelligence test, just a few questions to see how clever they are, and if they get the questions wrong… I think we know what happens next.

But to be fair and give my girls a chance to save themselves I asked a 4th really easy question – little did they know that the answer would be changed at the last moment to guarantee they got it wrong and ended up being gunged.

After being punished for failing the test they were stripped down to their bikinis and covered again in another tank-load of multi-coloured gunge.

For these videos the actual tank (the bit on top) has been rebuilt to be bigger and stronger, so there is more gunge per-tank in every scene, and it was filled to almost overflowing.

The photos are all original size and the video clips show the gunging from the front and above.
