Quizzes - Jumping the Shark

* This show jumped the shark a lot. It swirled around a lot down there in the depths. But it was a good show! It married people to each other and had a lot of bar fights. It was a mayhem, really. I think it jumped the shark when one of the characters went into a germ-free "bubble". Which show?
* This show jumped the shark when Lily Tomlin stepped in. It could've jumped it when Avery was born, but they handled that well. Often when they throw a baby into a hit show it gets all gooey and pretty awful. Which show did Lily take a part in?
* This show shark jumped when a sperm bank child showed up. And its jumping even more when the two main characters are considering having a baby. I tell ya. Kids can ruin a show! Which one am I talking about?
* This one jumped the shark when a wrecking ball came crashing into the hospital when a terminal cancer patient was walking in there and narrowly missed it. Which one?
* This one jumped the shark when one of the secondary characters, a love interest, was discovered to be someone in the witness protection program. Which one?
