On Monday's Heart Breakfast Su decided to audition Martin to be the new voice of Thunderbirds.
Actor Brian Cobby who was the voice of the speaking clock for 23 years and the man you said 'Thunderbirds Are Go' on TV sadly died at the age of 83. So Su thought Martin might be able to take over from him.
No one just gets given a job though, you must auction first...
So what do you think? Su and Alex weren't very good but do you think Martin could do it? Let us know below.
