Furinkan notes that: ""Yet you're hiding your true self. In other words, your performance is... lacking face!" - This is a complex pun. Mr. Kariya is talking about how the poltergeist hides himself behind his glasses and bald cap and obscures his identity before saying he is lacking face (in a literal sense). The term he uses "lacking face" (顔見世の場/kao mise no ba) is a phrase that also means "making ones debut"."

So, yeah, the joke was funnier in Japanese. Maybe not much funnier...
