This is a VERY hard trick to do, but well worth the time to see it. Go to Course 5 (Big Boo's House) and run into the little house off to the left. Take the elevator down, and then get back on it. As the elevator goes up, switch the camera to behind Mario (this is for the purpose of clear directions). Watch for when the ceiling pops into view. About a second before the elevator stops, run toward the black strip it follows and jump and kick the wall. Your goal is to bounce as far back as possible so that Mario's head gets caught between the elevator and the ceiling when the elevator stops. Make sure to hold the direction you ran all the way through the end of the trick. If done correctly, Mario will get stuck between the elevator and the ceiling, walking along in mid-air. You can punch, but if you jump you will fall down, where the elevator has mysteriously teleported down. However, if you duck, you will teleport down. Good Luck!!
