A U.S. mother鈥檚 tweets have gone viral after she shared photos of a seemingly kid-friendly picture book her son received from his grandma, in which she found a variety of colourful illustrations of animal saying a variety of colourful and inappropriate phrases.

The book, called 鈥淚f Animals Could Talk,鈥� features 96 pages of kid-friendly animal illustrations accompanied by vulgar and, some adults might say, hilarious things.

The more safe-for-work quotes include:

鈥淚 might have a coke problem鈥� 鈥� polar bear

鈥淪omeone get my Epipen!鈥� 鈥� blowfish

Her initial tweet about the book has been retweeted more than 50,000 times and liked more than 141,000 time since Tuesday night.

Tiffany says her six-year-old daughter tried reading the book, but said 鈥淚 don鈥檛 even know what this means鈥� after the first page.
