Naturally these are loose interpretations, and I don't have a match for some, so don't feel left out.
Looney Tunes
Pepe Le Pew - Doggett (they're both European, they're both always hitting on someone, and they both stink
)
Porky Pig - R.C. Merchant (yes, I thought of Daffy at first, but Porky's stuttering and Ronnie's style of writing just seem to go together)
Petunia Pig - Sister Grace (not only a down home girl and a sweetheart, but there's an inside joke to this as well)
Foghorn Leghorn - Ash (a big cock with something to say about everything, who keeps trying to get into the hen house but usually ends up in the doghouse)
Bugs Bunny - Allhallowsday (Always good for starting something and rolls with the punches well)
Marvin the Martian - CheezeFlixz (not only destructive, in his own sweet way...ahem..., but I felt it necessary to give him a character who is black)
Bosko - Trekgeezer (the original Looney Tunes character...meaning oldest
)
Blacque Jacque Shellacque - AndyC (gotta love them Canadians)
Tweety - Paquita (appetizing and sweet)
Sylvester the Cat - Me (draw your own conclusions b***hes)
Granny - Andrew (always having to keep an eye out for Sylvester and try to keep him under control...which we know will never happen
)
I missed quite a few of you, but somebody may fill in the blanks.
