"Dab Andy" was the online persona of a decorating teacher who had his own internet site and claimed to get ten million hits a day for his DIY lessons. Steve McDonald, determined not to employ Tony Stewart to redecorate the ladies' loos in the Rovers, decided to do the job himself, using Dab Andy as his guide. Liz McDonald, Michelle Connor and Anna Windass had severe doubts that he would succeed.
Steve confidently went through Andy's tutorial, quickly using terminology such as "back-buttering" the tiles and proudly showed off his efforts to his mum and girlfriend, just before the entire collage fell off the wall. They had no option but to call Tony in who was derisive of attempting to carry out such a job based on Andy's guidance.
In January 2022 Craig Tinker watched one of Andy's other videos, this time regarding how to remove the waste trap from a sink.
