Favorite old school animation...
I grew up with Lonney Tunes - I loved me some Yosemite Sam. And Foghorn Leghorn was another favorite of mine as a child.
I also have to say, DUCKTALES friggin' rules. Especially the theme song XD And what about Rescure Rangers? Or Gummi Bears? Loved those.
One that is quite obscure, and I actually found it on DVD, is The Adventures of David The Gnome. OMFG I loovveeedd it as a kid!! There was a little mini movie also called The Gnome's Great Adventure. My mom had the Gnome book when I was growing up... So I was infatuated with the myth... The cartoon was a natural transition. ;P
