Social media is a minefield of bad grammar and celebrities are as guilty as anyone else. Red Balloon, a leading English school in Brazil, asked 8-13 year old students to check their idols’ tweets, and then reply to them with grammar corrections and videos.

Celeb Grammar cops had hundreds of retweets and a number of websites posted their tweets and videos. The campaign resulted in a huge waiting list for kids who wanted to enrol at the school.
