Never Bathe on Saturday - S4-E27
Other mistake: When Laura is in the bathtub you do not hear the water running, or the water draining from the tub. Also, Laura's foot size (a size 6-7 same size as my foot size) would be too small to get stuck in the faucet. Also, when Laura and Rob are at their house if Laura's big toe was actually stuck in the faucet her toe would have been hurting bad enough to not put her shoe back on, but both shoes were on.
Never Bathe on Saturday - S4-E27
Other mistake: When Laura is stuck in the bathtub, she tells Rob "there's a full length mirror on the back of the door" Rob runs full speed right into the door with his shoulder. Yet with his weight, height, BMI he would have immediately knocked the mirror off the door the 1st hit, not after the 3rd time when Rob put his elbow on the door. Also the mirror wouldn't have taken 9 seconds to finally fall with the height of the door. (00:17:34 - 00:18:26)
