Invisible Man And Psychiatrist

A guy walks up to the receptionist in the Psychiatrist’s office and says:

“I’m the Invisible man and I’d like to talk to the Doctor”.

She pokes her head into the Psychiatrist’s office and says:

There is a man here who wants to talk to you and he claims he’s the Invisible man.

The Psychiatrist replies:

“Tell him I can’t see him right now”.
