Watch carefully the part when the bald thief (Harry) tries to break into Kevin's house through the front door. Kevin has placed a heating coil on the other side of the door.. When Harry touches the door knob, expecting it to open, unawares, he places his hand DIAGONALLY across the knob, which has an "M" on it.. His palm gets burnt but when the camera focusses on it, it reads as an "M" where it should be sideways, quite like an "E"..
