Ordering things to be custom made can be hit or miss - you might be lucky and get a beautifully made item that is exactly what you wanted, or you might get something that isn't really what you were after at all.
But by the time it arrives, it's often too late to do anything about it.
Yup, thanks to a brilliant bit of miscommunication, one woman says her mum was given this lovely green and white weed-themed cake complete with a My Little Pony character smoking a joint, instead of one based around the popular Disney cartoon.
Sharing the funny story on Facebook, Kensli Davis, the lucky recipient of the birthday cake, wrote: "I haven't had a chance to tell y'all about our experience this weekend with my birthday cake.
"So my mama called and ordered me a cake telling them how much I loved Moana. (Because really I do) Well needless to say these people thought she said marijuana. That ice cream cake was still good though."
Fair play, though, they've done a pretty good job. I imagine if Kensli did love weed; she'd be delighted with this.
The post has quickly gone viral, picking up more than 11,000 shares and 10,000 likes; while hundreds of people commented on the post to say it was 'hilarious' others said they were keen to have the cake made for their own birthdays.
While this example stems from a simple miscommunication, last year another green birthday cake went viral for a different reason.
Aussie dad Shane Hallford forked out AUD $49 (£28) for a frog-themed cake from his local Woolworths store in Tamworth, New South Wales, expecting to something pretty cute for his three-year-old son Mason's birthday.
However, when he came to collect it, he was presented with this very half-a***ed job.
Shane said: "I went down to pick it up on the morning of Mason's birthday party. I was in a rush getting extra supplies and didn't actually check it at the store because it was in a huge box.
"When I got home, I opened it up with my wife and we were both mortified. They had this tiny little number three, along with a smiley face, all written in green icing. It would have taken five seconds to do."
Thankfully, Shane was able to salvage the cake by buying some extra icing and getting creative.
It's trickier than it looks this cake buying malarkey, isn't it?Featured Image Credit: Facebook/Kensli Davis
