I'm not sure. The problem with that statement, is that the episodes have different plots.
I can also see some people on here not allowed to watch that show because of its content, and it's cussing.
The A plot in family guy is different, The B plot of Family Guy, is Very similar to inSPONGEiac. Just the way it happened was different.
No, but in Fear of a Krabby Patty, he was using the ingredients in the Krusty Krab wrong, like in InSPONGEiac.
