If I were to list those who had the greatest influence on my childhood, and therefore my entire life, I guess my Mum and Dad would take the top two slots, but vying for the number three position would be, amongst very few others, Fred Quimby.
However, it's not going to be much of a thread if I suggest we all put forward our favourite producer of short cartoons, so instead we'll go for our favourite cartoon characters.
It's a tough choice, actually. But, until I change my mind, I'll nominate this one ...

A metal image of Daffy hangs from my keyring, in just this pose. I really ought to be embarrassed about that, I suppose.
