My fave LT characters are a little obscure. I love Marc Antony and Pussyfoot - the animated expressions of that dog are just fantastic, and the little storyline of dog meets cat, dog hates cat, cat beguiles dog, dog become's cat's champion - well, I just love it.
Similar to Pussyfoot, I also love the toon about the kitten raised by an eagle, who learns to fly by spinning his little tail like a propellor. I love how the story progresses and he grows up to be a very heroic 'whatta guy' type cat, who saves the day and wins the girl. Very funny and very watchable.
I also adore Bugs, Marvin and Wile Coyote.
Least fave LT character: Tweety. Smug little goody-two shoes. And nearly all WB women's wear has Tweety on it! Meh! Not all women love Tweety, WB!
