This is totally one of the worst episodes that I have ever seen in a sitcom. First of all this whole barny story is extremely unethical and cheap. But besides that! The toothbrush story. Omg! Sooo lame. 3 people using the same toothbrush for 8 years. Because its rational for people not to replace their toothbrush ... and if this happened it would not have been noticed by the other 2... and so many other details...
