The top everyday lies Brits admit to telling include “I forgot”, “I'll do it tomorrow”, and “I am listening”, research has found.
As many as 80% of Brits admit to telling fibs, doing so an average of 34 times a week, according to a poll of 2,000 adults.
Other common mis-truths include “I'm busy then”, and “I haven't got any change” – as well as not being honest about how much money you spent on something.
And two in five (42%) believe they are convincing when it comes to being dishonest – but a further 43% they are not very believable fibbers.
The biggest reasons for lying include not wanting to offend others by revealing what you really think (52%), to keep people onside (34%), and to avoid a telling off (32%).

But more than half (51%) feel guilty when they don't tell the truth – according to the research commissioned by Uber Eats, the only food ordering service to deliver Honest Burgers.
And this might be with good reason – as two in five (42%) revealed a lie has come back to haunt them.
Following the findings, a pop-up booth called “Tasty Truths” will open to the public where they can confess their fibs – with those who do so receiving a free burger.
The study also found those polled are most likely to lie to a partner – with almost half (46%) of those who admit to lying having done just that.
Work colleagues (44%) came second, followed by employers (36%) – while 23% confessed to fibbing to a police officer, and 14% to their child’s teacher.
Other frequent mis-truths include “Nice to see you”, “I got stuck in traffic”, and “I don’t know what happened there”.
However, more than a third (37%) believe it’s never okay to stray from the truth, with 50% claiming honesty is always the best policy.
The study, carried out via OnePoll, also found nearly three-quarters (71%) believe they can tell when someone else is being dishonest.
The “Tasty Truths” pop-up will be in Liverpool on Thursday, 27 October, and London on Friday, 28 October, between 11:30 and 14:30 on both days.
