2000's Cartoon Network particularly the 2003-2007 era
Grim Adventures of Billy and Mandy, Ed, Edd and Eddy, Foster's home, K.N.D, Teen Titans, Sumarai Jack, Chowder + Powerpuff girls, Dexter Lab etc. Were still on air till 2004-6
I remember being perched for Fridays CN where all my favorite shows had new episodes
CN plunged deeply after that but it's line-up is still great today, Adventure time, Regular show, Steven Universe, Gumball etc. Are all grade A shows glad CN still cares unlike the other two (Nick, DC) which are just trash now.
they only aired a few episodes but i still remember ha 
I Miss my childhood 
My favorite shows all time
