It's one of the most embarrassing thing that can happen to anyone when a microphone is live and a camera is rolling - the accidental uttering of a swear word.  And it caught Tom Hanks on 'Good Morning America' Friday morning.

Hanks was on the show to promote the movie 'Cloud Atlas' and the discussion turned to a joke about swearing being okay if it's done with a foreign accent.  Hanks slips into a French accent and lets one slip.

Hanks is instantly embarrassed and swore he'll never do another live shot on TV without a seven-second delay.

Watch the video and let me know, was it really so bad?  I certainly don't think so - Hanks has such a squeaky clean image and it was obviously an accident.
