Name: Real name unknown (Paula's Father)
Voice: Sam Seder

Paula's dad jumps from a rambling gambler to a pathetic drunk to a crazy old man. I think all the "old people" bases are covered.

Life Through A Fish Eye Lens - Paula comes over to ask to money; he gambles with Brendon (and wins)
Breaking Up Is Hard To Do - Is divorced by Doris; ends up living at the Small house for awhile
Cho and the Adventures of Amy Lee - Is beaten up by Brendon
