Show Me The Money Shirt

Do you remember Tom Cruise in the film 'Jerry Maguire'? The famous scene where a painfully young Cruise is reduced to screaming 'Show me the money' into a phone?

We gave this some considerable thought (well, three minutes before going down to the pub) and concluded the money could only ever have been in one place. Hiding in the polka dots.
