At 16:58 after Wilson says "Truly a mystery, why would anyone do something just to aggravate people?" his left sleeve is rolled up and he begins to roll up his right sleeve, but when the camera angle changes he is rolling up his left sleeve and his right sleeve is not rolled up at all.
When Dr. Cuddy walks into the lounge to find Dr. House watching a soap opera on TV, she picks up the remote control and presses the power button to turn off the TV; There is a Beep sound. When Dr. House presses the button on the remote control to turn the TV back on, there is a Click sound. After Dr. Cuddy leaves, House presses the remote control to turn the TV off; The remote control neither beeps nor clicks.
In this episode Dr. House plays a record to induce a seizure in a patient, but no record or record player is seen in the room. Instead House is seen using a bass guitar amplifier and speaker cabinet. It makes no sense for the sound heard to be coming out of that equipment. Even further: while House acts he's plugging into the mains, the amplifier wasn't, a LED would have indicate that on the face plate, and the equipment would have required both of the switches ON to operate.
