We took a white plastic bucket and keel hauled it upside down with a 
rope under the bow below the water line at the side of the boat to form 
an air lock. Then, donning appropriate bathing costumes, we jumped 
over the side with the microphone covered with two condoms and came 
up inside the bucket. The sounds in the harbour were distant metallic 
clinking, throaty motors purring, water slapping our boat's hull. Then 
inside the bucket came a suppressed scream as the microphone joined 
our shocked heads in the air lock. We did this about eight times which 
exhausted about everything you could say about being inside a white 
plastic bucket. I was able to stay in the bucket about 30 seconds before 
all the air was exhausted. Hank breathed less and stayed longer.

The rest of that show was done at home using the telephone, 
microphones and a small speaker, all covered with condoms in the bath 
tub. All sound for the show was guaranteed to have been recorded under, 
or passed through, water before it was broadcast. 37
