Bizarre Interview Mistakes

HR.BLR.com's HR Strange But True! column this week had the "10 Most Bizzarre Interview Mistakes" as determined by Careerbuilder.com:

Candidate answered cell phone and asked the interviewer to leave her own office because it was a "private" conversation.
Candidate told the interviewer he wouldn't be able to stay with the job long because he thought he might get an inheritance if his uncle died-- and his uncle wasn't "looking too good."
Candidate asked the interviewer for a ride home after the interview.
Candidate smelled his armpits on the way to the interview room.
Candidate said she could not provide a writing sample because all of her writing had been for the CIA and it was "classified."
Candidate told the interviewer he was fired for beating up his last boss.
When applicant was offered food before the interview, he declined saying he didn't want to line his stomach with grease before going out drinking.
A candidate for an accounting position said she was a "people person" not a "numbers person."
Candidate flushed the toilet while talking to interviewer during phone interview.
Candidate took out a hair brush and brushed her hair.

Just curious what the most bizarre interview mistake you have seen has been. 

I have had the toilet flushing before.  I have also had a candidate use the "F" word in just about every sentence like it was just a word that everyone uses all the time. When I asked him to please refrain from using the word, he asked me why.
