I can really only remeber a VERY small bit of it, and I honestly can't say for sure it was looney tunes, but I am almost positive. There was a ghost in it who would yell "BOO!" and had a really silly laugh right afterwards and it sounded somewhat barney rubble-ish. I know that may not be too much to go on, but I'm hoping one of you who is really familiar with cartoons can help me out. I'm trying to remember what its from and its driving me nuts! thanks in advance if you can help.
