thought nypd blue was the 15th, so i am gonna guess Homicide

I'm guessing Chappelle's Show, that sketch where the crack dealer pleads the fifth like the Enron executives. Showing just the title card is a misdirection to make us think it's a serious cop show.

wildcard:

How I Met Your Mother?

nope, older.

Here's another clue since dek's getting eager for his turn

The Adventures Of Pete & Pete

ED.... but its not your turn

As to josepotato's screenshots...

yep, well done

Hint: This show came and went...extinct.

EDIT: I put a white box over the network logo, so as to make it a little tougher.

Based on your clue, and the fact that it is 4x3, I'm going to guess: Dinosaurs.

(If the shot was 16x9, I would have guessed: Cavemen.)

It was Cavemen. Guess the size was a little misleading, but I took it in a streaming player, so that's why it was sized that way.

Other screenshots I was going to use:

My Name is Earl?

Nope, not My Name is Earl.

There might not be very many people on this forum who've seen this show, though I did see it mentioned in a thread in Movie Talk. The most recent (3rd) season ended last December. (I liked seasons 1 and 2 better.)

the mighty boosh?

Yep

It's Always Sunny in Philadelphia, of course.

yup
