Playing submarines in the bath with earphones on TTWD, sounds very realistic and shows your patriotism.
Did you also have a mike on to shout, emergency, emergency as you surfaced?
I note that your technical knowledge has identified some of your ‘entertainers’ shortcomings, perhaps you could offer some advice to him if it didn’t end up with you wearing his amplifier!
Good to see that you managed to gain some enjoyment from the evening too.
