I have cartoons I really love just for themselves and others that I love for that reason and the clowny inspiration I can get from them.
I am a huge 80s cartoon fan. Transformers, GI Joe, Get Along Gang, Shirt Tails, Captain N, Dungeons and Dragons, Gummy Bears, Tail Spin, MR T, Care Bears, Beverly Hills Teens, the list goes on and on! Love those 80s cartoons.
Slightly more recently I really enjoyed Darkwing Duck and Gargoyles.
For inspiration I always turn to Goofy. Just about any cartoon starring him is hilarious and has tons of material that gets me to laugh. I am particularly fond of the cartoons in which he is trying to build something using directions or an audio tape or Narrator and any of his "How to" cartoons. I have written a couple short acts based on those ideas and they are some of my favorite.
Here is a link to a whole bunch of his Goofy How Tos. They really are tremendously funny!
