Have you ever been sat in a crowded McDonald's just about to tuck into your Grande McChicken Super Tex-Mex Barbecue meal, and while chaotic scenes of depressed parents grappling with their rampant offspring go on around you, thought, I should do this every day?
No? Of course not, it sounds God awful. It would be like going to a children's birthday party every day and have happy meals funneled directly into your mouth, while your eyes are pinned open and you are made to watch clown horror It - the Tim Curry original - on repeat. Over and over.
No one likes kids and no one likes clowns.
But aside from the obvious negative mental impact that would cause, one man says the golden arches have done wonders for him physically and helped him lose over a stone by only eating McDonald's meals for a month.
Ryan Williams, 29, launched his fast food mission to try and disprove Morgan Spurlock's famous 'Super Size Me' challenge, which saw the director also eat nothing but McDonald's for 30 days - and gained almost two stone.
But the Cheltenham postman didn't agree with the film and decided to prove it is possible to get in shape in 30 days on a McDonald's-only diet.
He said: "I've wanted to do this for a few years, but I never found the right time.
"Ever since I saw Super Size Me, I thought that the way he [Morgan Spurlock] did the experiment, was unfair.
"He ate 5,000 calories a day and didn't do any exercise, I didn't feel like it was a surprise he became so unhealthy."
Spending almost £20 a day on fast food he ate everything on the menu at least once and finished the month one stone two lbs lighter than when he began, having lost just over two percent of his body fat, compared to Spurlock who gained two stone.
However, on closer inspection the comparison between the two isn't that fair.
Whereas Spurlock supersized every meal to increase the calories content, Ryan never ate more than 2,500 per day, and while the American never worked out, the postal worker woke up at 4am every day to go to the gym.
Not quite the same really, are they?
Ryan said: "I weighed 14st 2lbs at the start of the challenge and 13st at the end. But my days throughout the challenge were very long.
"Prior to the challenge I was probably in the worst state I'd been in in a few years.
"My diet wasn't great, I would eat a lot of food - about 5,000 calories - in a day, lots of biscuits and junk food, and I wasn't going to the gym at all.
He added: "So for me, this challenge was partly about what I could do to help myself get back to that, whilst also having a bit of fun."
McDonald's have been contacted for a comment.
No matter what they say, for the good of your health you probably shouldn't do this.
