I don't usually do topical sketches but here's a quick attempt. Don't know if it's any good.
BRITNEY SPEARS WALKS INTO A ROOM, THE INTERVIEWER IS SITTING AT A TABLE WITH PEN AND PAPER. IT IS CLEAR BRITNEY HAS A WIG ON, SHE IS ALSO DRESSED INAPPROPRIATELY.
Interviewer
Hi (GETS UP TO SHAKE HER HAND)
Britney
Hello, sir (IGNORES HAND SHAKE AND SITS DOWN)
Interviewer
So, (SITS DOWN) Why have you decided to apply for this particular job?
Britney
Well, I fancied a change. The workload was appalling, I had to work at least twice a month. (LAUGHS)
Interviewer
OK, (WRITES SOMETHING DOWN ON PAPER) What do you believe you could offer the business?
Britney
I'm a bit of a character, a bit wacky, I'll keep the workforce entertained (LAUGHS)
Interviewer
To be honest Mrs Spears-
Britney
Oh you can call me Britney.
Interviewer
OK, Britney, I dont think you are taking this seriously. Why did you apply for this job if you were not going to try and make a "good impression" at the interview.
Britney
(LAUGHS) OK, I'll tell you the truth, I've been out of the news for the last couple of weeks and needed to do something "crazy" (LAUGHS), So I said why not apply for a job at Northern Rock?
Interviewer
Get out! Just, get out!
(BRITNEY WALKS OUT, INTERVIEWER IS AT DOOR AND SHOUTS)
Interviewer
Debra send in Mrs Winehouse.
