Not to be Confused with Our Secret Basement Laboratory

And this Grandpa John is not to be confused with our Grandpa John:



The irony is that Grandpa John's curricula is approached from a Christian perspective and we do use it in our secret basement laboratory's child care center.

Other unrelated Grandpa Johns:

Grandpa John's Kettle Cooked Pork Cracklins.

Grandpa John's Junkyard. (Cue Sanford & Son theme music.)

Grandpa John's Rib Shack in Peoria.

Grandpa John's Amazing Maze (& Pumpkin Patch).

Grandpa John's Swiss Mountain Retreat.

Grandpa John's Wooden Toys.

Grandpa John's Cafe.

However, although this guy is a grandpa and was arrested for being a john, we don't consider him a legitimate Grandpa John.
