The best episode of Seinfeld was "Bizarro Jerry"

It had Bizarro Jerry, Man Hands, George finds the Supermodel Hidden City, Kramer gets pulled into a corporate job.

The best episode of Johnny Quest was Robot Spy.

The best episode of ST:TNG was The Best Of Both Worlds, Part 1. They could have ended the series on that cliffhanger.

The best episode of ST:DS9 was "In the Pale Moonlight." Tightly written, extremely well-acted and it set DS9 apart from the rest of the franchise with the ugliness of war and diplomacy.

Gotta go with "The Boyfriend" for this one. Newman, Keith Hernandez, a second spitter, Vandalay Industries... one of the top ten funniest episodes of ANY tv show ever.

The best episode of Arrested Development was "Bringing Up Buster."

Those are close seconds to "The Contest" to me. Glamour Magazine, John F. Kennedy Jr., Jerry dating a virgin, "I'm out", etc. Also, "The Strike" featuring Festivus and No Bagel and "The Comeback" featuring the best Seinfeld line of all time: "The jerk store called, they're running out of you!"

The best episode of Friends is "The One Where No One's Ready".

"Hi! I'm Chandler! Could I BE wearing any more clothes?"

The best episode of Judge Judy is the one where the defendant explained to Judy that he "GENTLY threw the rock at the plaintiff's car."

The best episode of The Shield is probably the finale. So fucked up in so many ways.

The best episode of Doctor Who is "The Girl in the Fireplace".

The best episode of The Simpsons is "Last Exit to Springfield." Lisa needs braces, dental plan.

The best episode of The Big Bang Theory is "The Einstein Approximation" with the ball pit.

I'd go with "Cape Feare". Sideshow Bob has never been better. Plus, the witness protection program and everyone trying to kill Bart.

Second is "Marge vs. the Monorail".

+1

The best episode of "How I Met Your Mother" is "Swarley" followed by "Slap Bet" (featuring Robin Sparkles)

I can go with this. The angel statues episode was hyped too much to me, so I didn't get the full effect.

The best episode of Doctor Who is "City of Death."

The best episode of modern Doctor Who is a harder call. I'll pick "The Empty Child/The Doctor Dances."

Adventures of Superman : "The Stolen Costume".
The ending reminds me of the punchline of a joke when Batman says
to Superman, "Clark, sometimes you can be a real son-of-a-bitch".

Nice one.

For Friends, I would go with the episode where ... well, I don't know the title ... but it's the one where they watch the video of Ross and Rachel to learn who came onto who.

Joey: "Onto whom."

[everyone looks at him]

Joey: "Yeah, that's right."

Good choice. A lot of building hysterical humor in that one. I love the hiking in the Alps pickup story.
