Tried listening to a bit of this but found it unbearable. My sides cant take laughing that hard for very long. This show could be summed up as "one fool interviews some other fools".
Interestingly the preamble talks about asking "do they work" but in the parts I listened to the interviewer never once asks for supporting evidence of this nature. I presume the BBC doesnt want this programme to be taken seriously, even its name suggests that!
If you don't tell them what you think then your view certainly wont be heard regardless of how they respond.
