Scriptwriters capitalised on the rivalry between the characters when, in 1986, Mike married Ken's daughter Susan, a union that Ken strongly opposed. Numerous fights between Ken and Mike were featured, and Briggs has suggested that they became famous for their brawls. The first fight between the pair occurred in 1986, when Ken confronted Mike in his factory about Mike's maltreatment of his daughter. Of the confrontation, Briggs has said, "It was a classic – Baldwin getting it in his own territory, the factory. It took a lot to get Ken angry but after the way Mike had treated his daughter, he was furious. He marched into the office and let him have it. This was one of those rare times he caught Mike off-guard." Mike was shown to get revenge on Ken, though it took a further four years before he could do so on-screen. In a scene which aired in 1990, Mike punched Ken, knocking him over a table in the Rovers Return public house. Briggs has suggested that he and Roache became old hands at doing on-screen fistfights, and that both really enjoyed doing the stunts. According to Briggs, no choreographers were ever used. In 1998 one incident left Briggs with an injury after he fell backwards.
