my wife watched some youtube videos and proclaimed she would feel comfortable giving it a go on my mop. She started cutting ever so slowly , and carefully on my hair not making very much progress with the cheap clippers, i asked her for the clippers to get this one hair sticking out, i then took them and ran them down the middle of my head, giving myself a reverse mohawk, My wife screamed and said "Why did you do that !!".. i laughed and asked her to finish it off the same all over my head with the # 3 attachment. then we both had a good laugh about it.
