Separated at birth

Tulkinghorn has been alerted by an anonymous source to the uncanny likeness that SJ Berwin financial services partner David Calligan bears to Ally McBeal star John Cage. Like Calligan, Cage - aka 'the biscuit' - is a lawyer. But after that the similarities end, as Cage is a litigator while Calligan is a financial services expert. However, Calligan does act for a number of US companies, so are they, in fact, one and the same? Tulkinghorn needs one final piece of evidence: does Calligan have any frogs as mates, pick his nose or use a remote control toilet flusher? If anyone knows, please get in touch.
