Everybody has already listed some of my favorites.
Don't get pissed at me for saying this but there was once a cute kids show called "iCarly" that was created by Dan Schneider. I watched it when I was about 9, so I ended up watching it all the way up to when I was 15. The last episode had me upset because it had to end.
And I'm ****ing pissed on how it ended. It was ****ing depressing
The episode ending with her watching reruns of iCarly webcasts from the beginning

and then she closed her computer. And was on a plane with her **** ugly dad.
7 seasons was not enough.
Dan Schneider's productions are amazing. But nothing will ever come close to Drake and Josh and iCarly.
