Silly Job Interview is a sketch that appears in the fifth episode of Monty Python's Flying Circus, "Man's Crisis of Identity in the Latter Half of the 20th Century."
An interviewer (John Cleese) tells the audience that he enjoys interviewing applicants. One named David Thomas (Graham Chapman) then enters. The interviewer has him sit down, stand up, then sit back down. He continues with antics such as repeatedly greeting him, ringing a bell, abruptly counting down, and making a strange noise. Soon, it is revealed to David that there are actually no vacancies to be filled.
