It's 2017, we all know how to send a text. Or do we? Clearly these people are having trouble understanding the concept, with hilarious consequences. This Twitter user Cassidy Baldwin was innocently trying to show her mum her arm, but instead got someone entirely different.

What a kind stranger, caring about her wellbeing like that.

And Cassidy isn't the only one to suffer at the hands of a missed digit. This next one might have forged a brand new friendship that went over the generations.

As a rule, never talk about sex toys with someone unless you're sure you have the right number. Unfortunately this poor person didn't get the memo, and will not be making a sale today.

Even though Jeff wasn't real, that salesperson was catering to his needs and should get a customer service award. PSA, though, please stop texting random numbers and check next time.
