Crabby Appleton, the meanest man in the world!
'My name is Crabby Appleton,
I'm rotten to the core
I do a bad deed every day,
and sometimes three or four.
I can't stand fun for anyone,
I think good deeds are sappy,
I laugh with glee, it pleases me,
when everyone's unhappy!'
He was from Tom Terrific (with Manfred, the Wonder Dog) which was on Captain Kangaroo!
