It is time for Isla to take her turn under the gunge and try and win the cash in Jeremy's super prize quiz game:

Who Wams to be a Millionaire!

The rules are simple; guess the number in Jeremy's head to win a million pounds and avoid a gunging. Up till now, we've seen a 100% failure rate with each visitor finding themselves on the receiving end of a slimy dousing! [sarcasm] I wonder if Isla will manage to guess!?
