A hair gel commonly used by grandpas. Often their grandsons comment on how good their hair looks. It is often sold in jars with Ed Crankshaft's picture on them. He has been known to use it.
Nelson: (let's out a big wolf whistle) Whoah, boy! You're getting all gussied up. What's going on?

Ed: I'm fixing my hair. I'm going bowling with a bunch of the bus drivers. You know, your Uncle Rudy and your Aunt Lena and all them.

Nelson: Wow! What's that stuff all in your hair?

Ed: (starts laughing) That's my Grandpa Goo. Hey, wanna come with me? The gang's gonna flip when you use this.

Nelson: Nice! (bends his head down) Let's massage this into my mop!

Ed: (growling) That's the ticket! No grandpa is complete without a good hairdo. All you need is some Grandpa Goo!
