Try saying ‘She sells sea shells on the sea shore’. A tongue twister is tough and when we cannot say it perfectly, we end up saying hilarious words which make the game even more interesting. However, a tongue tied situation is totally different one and most of the time can land us in embarrassment. The slip of tongue can at times be so awkward that we ourselves do not believe our ears and there we see people laughing their hearts out at what we said.
News is something which goes on air LIVE and there is hardly any time to mend the mistakes so a news reader or reporter has to be too vigilant about their speech. If they somehow get tongue tied, things like these are ought to occur, making the audience and the crew laugh in unison.
